AI-Enhanced Search Strategy for iDempiere ERP (2025)

Date: 2025-12-12 Version: 1.0 Status: Strategic Analysis - Future Roadmap Context: Cloudempiere Search Index Plugin Architecture


Executive Summary

The Cloudempiere Search Index plugin's provider architecture (ISearchIndexProvider) positions it perfectly for AI/ML integration in the 2025 landscape. The existing OSGi plugin framework can be extended with modern AI search providers to deliver:

  • Semantic Search - Understand intent, not just keywords
  • Vector Search - Find conceptually similar products/documents
  • RAG Integration - AI assistants grounded in ERP data
  • Natural Language Queries - "Show me unpaid invoices from last quarter"
  • Multi-Modal Search - Text + images + structured data
  • Personalized Results - Context-aware ranking per user/role

Key Insight: The plugin's provider architecture (PostgreSQL, Elasticsearch stub) can be extended with AI-powered providers (pgvector, OpenAI embeddings, local LLMs) without changing core ERP integration.

Strategic Value:

  • Transform ERP search from keyword matching to intelligent retrieval
  • Enable AI copilots grounded in real business data (RAG)
  • Competitive advantage: AI-powered ERP search in 2025
  • Cost-effective: Leverage existing PostgreSQL + pgvector (no new infrastructure)

Part 1: Current Architecture Readiness for AI

Existing Provider Pattern (Perfect for AI Extension)

// Current architecture
public interface ISearchIndexProvider {
    void createIndex(Properties ctx, SearchIndexData data, String trxName);
    void updateIndex(Properties ctx, SearchIndexData data, String trxName);
    List<ISearchResult> getSearchResults(Properties ctx, String searchIndexName,
                                         String query, boolean isAdvanced,
                                         SearchType searchType, String orderBy);
    // ... other methods
}

// Current providers
- PGTextSearchIndexProvider    // PostgreSQL full-text search
- ElasticSearchIndexProvider   // Elasticsearch (stub)

// NEW AI-powered providers (2025+)
+ PGVectorSearchProvider       // PostgreSQL pgvector for embeddings
+ OpenAIEmbeddingProvider      // OpenAI embeddings API
+ LocalLLMProvider             // Self-hosted LLM (Ollama, llama.cpp)
+ HybridSearchProvider         // Combine keyword + semantic + vector

Why This Architecture is AI-Ready

1. Pluggable Providers

  • ✅ Can add new AI providers without modifying core plugin
  • ✅ Each provider can use different AI technology (embeddings, LLMs, etc.)
  • ✅ Providers can be combined (hybrid search)

2. OSGi Service Registry

  • ✅ Dynamic provider discovery
  • ✅ Hot-swapping providers at runtime
  • ✅ A/B testing different AI models

3. Multi-Tenant Isolation

  • ✅ Each client can use different AI provider
  • ✅ Data isolation guaranteed (AD_Client_ID)
  • ✅ Per-client AI model customization

4. API Integration

  • ✅ REST API already supports search index
  • ✅ Can expose AI search via OData endpoints
  • ✅ Mobile apps can use AI-powered search

5. Event-Driven Updates

  • ✅ Automatic embedding generation on data changes
  • ✅ Real-time AI index updates
  • ✅ No batch processing needed

Part 2: AI/ML Integration Opportunities (2025 Paradigms)

Opportunity 1: Vector Search / Semantic Similarity

What It Is: Transform text into high-dimensional vectors (embeddings) that capture semantic meaning. Similar concepts cluster together in vector space.

Example:

Traditional keyword search:
  Query: "red rose"
  Finds: Products with exact words "red" and "rose"
  Misses: "crimson flower", "červená ruža" (Slovak)

Vector/semantic search:
  Query: "red rose"
  Embedding: [0.234, -0.891, 0.456, ...] (1536 dimensions)
  Finds: "crimson flower" (similar embedding)
        "červená ruža" (cross-language semantic match)
        "bouquet" (related concept)

ERP Use Cases:

  1. Product Discovery

    User: "Something for Mother's Day"
    AI: Finds flowers, chocolates, gift cards (conceptually related)
    Not just: Products with "Mother's Day" in name
    
  2. Cross-Language Search

    Query in English: "invoice"
    Finds: "faktúra" (Slovak), "Rechnung" (German)
    Automatic multilingual support
    
  3. Conceptual Parts Search

    Engineer: "component that reduces vibration"
    AI: Finds dampers, shock absorbers, mounting brackets
    Not limited to: "vibration" in product description
    

Technical Implementation:

// New provider: PGVectorSearchProvider
public class PGVectorSearchProvider implements ISearchIndexProvider {

    private OpenAIClient embeddingClient; // or local model

    @Override
    public void createIndex(Properties ctx, SearchIndexData data, String trxName) {
        // 1. Get text content
        String content = buildContentString(data);

        // 2. Generate embedding vector
        float[] embedding = embeddingClient.createEmbedding(content);
        // Example: [0.234, -0.891, 0.456, ...] (1536 dimensions for OpenAI)

        // 3. Store in PostgreSQL with pgvector extension
        String sql = "INSERT INTO searchindex_vector " +
                     "(ad_client_id, ad_table_id, record_id, embedding) " +
                     "VALUES (?, ?, ?, ?::vector)";
        PreparedStatement ps = DB.prepareStatement(sql, trxName);
        ps.setInt(1, data.getAD_Client_ID());
        ps.setInt(2, data.getAD_Table_ID());
        ps.setInt(3, data.getRecordID());
        ps.setObject(4, embedding); // pgvector type
        ps.executeUpdate();
    }

    @Override
    public List<ISearchResult> getSearchResults(Properties ctx, String searchIndexName,
                                                String query, boolean isAdvanced,
                                                SearchType searchType, String orderBy) {
        // 1. Convert query to embedding
        float[] queryEmbedding = embeddingClient.createEmbedding(query);

        // 2. Vector similarity search (cosine distance)
        String sql = "SELECT ad_table_id, record_id, " +
                     "       embedding <=> ?::vector AS distance " +
                     "FROM searchindex_vector " +
                     "WHERE ad_client_id = ? " +
                     "ORDER BY embedding <=> ?::vector " + // <=> is cosine distance
                     "LIMIT 10";

        // 3. Execute and return results
        // Results ranked by semantic similarity, not keyword match
    }
}

Database Setup:

-- Install pgvector extension
CREATE EXTENSION IF NOT EXISTS vector;

-- Create vector index table
CREATE TABLE searchindex_vector (
    ad_client_id INT NOT NULL,
    ad_table_id INT NOT NULL,
    record_id INT NOT NULL,
    embedding vector(1536), -- OpenAI ada-002 dimension
    metadata JSONB, -- Store additional context
    created TIMESTAMP DEFAULT NOW(),
    updated TIMESTAMP DEFAULT NOW(),
    CONSTRAINT pk_searchindex_vector PRIMARY KEY (ad_client_id, ad_table_id, record_id)
);

-- Create IVFFlat index for fast similarity search
CREATE INDEX idx_searchindex_vector_embedding
    ON searchindex_vector
    USING ivfflat (embedding vector_cosine_ops)
    WITH (lists = 100);

-- For even faster search with HNSW (requires pgvector 0.5.0+)
CREATE INDEX idx_searchindex_vector_hnsw
    ON searchindex_vector
    USING hnsw (embedding vector_cosine_ops);

Cost Analysis:

Approach Infrastructure Embeddings Cost Total (1M products, 1K searches/day)
OpenAI API PostgreSQL + pgvector $0.0001/1K tokens ~$50/month (embeddings) + $0 (search)
Local LLM (Ollama) PostgreSQL + pgvector + 1 GPU server $0 €200/month (GPU server)
Elasticsearch + Vector Elasticsearch cluster $0 (local model) €500/month (infrastructure)

Recommendation: PostgreSQL + pgvector + OpenAI embeddings (cheapest, best quality)


Opportunity 2: RAG (Retrieval Augmented Generation) for ERP

What It Is: Combine AI search (retrieval) with large language models (generation) to create AI assistants that answer questions grounded in your ERP data.

Example:

User: "Why is customer ACME Corp's balance so high?"

Traditional ERP: User must navigate:
  1. Customer window
  2. Find ACME Corp
  3. Check invoices tab
  4. Check payments tab
  5. Manually calculate
  6. Analyze patterns

RAG-powered AI Assistant:
  1. Retrieves relevant data (via search index):
     - Recent invoices for ACME Corp
     - Payment history
     - Credit terms
  2. Generates natural language answer:
     "ACME Corp has a balance of €45,230 due to:
      - 3 overdue invoices (€38,500) from Q4 2024
      - Payment terms: Net 60 (currently 72 days overdue)
      - Historical payment behavior: Usually pays within 65-70 days
      Recommendation: Contact accounts receivable department"

ERP Use Cases:

  1. Business Intelligence Assistant

    User: "Which products are underperforming this quarter?"
    
    RAG flow:
    1. Search index retrieves: Sales data, inventory levels, targets
    2. LLM analyzes and generates report with insights
    3. User gets actionable answer, not raw data
    
  2. Process Guidance

    User: "How do I create a purchase order for maintenance supplies?"
    
    RAG flow:
    1. Search index finds: Process documentation, examples, approval rules
    2. LLM creates step-by-step guide customized to user's role
    3. Links to specific ERP windows/processes
    
  3. Anomaly Detection

    User: "Are there any unusual transactions today?"
    
    RAG flow:
    1. Search index retrieves: Today's transactions + historical patterns
    2. LLM identifies anomalies (high amounts, unusual vendors, etc.)
    3. Generates alert with context and recommended actions

Implementation Example:

// New OSGi service: RAGSearchService
@Component
public class RAGSearchService {

    @Reference
    private ISearchIndexProviderFactory providerFactory;

    @Reference
    private ILLMProvider llmProvider; // OpenAI, Ollama, etc.

    /**
     * Answer natural language question using RAG
     */
    public RAGResponse answerQuestion(Properties ctx, String question) {
        // 1. Understand intent
        QueryIntent intent = classifyIntent(question);
        // Examples: FIND_RECORD, ANALYZE_DATA, EXPLAIN_PROCESS

        // 2. Retrieve relevant data
        ISearchIndexProvider searchProvider = providerFactory.getProvider("hybrid");
        List<ISearchResult> searchResults = searchProvider.getSearchResults(
            ctx,
            intent.getSearchIndexName(),
            question,
            false, // Use AI semantic search, not advanced syntax
            SearchType.SEMANTIC,
            null
        );

        // 3. Build context for LLM
        String context = buildRAGContext(searchResults, intent);

        // 4. Generate answer
        String prompt = buildPrompt(question, context, getUserRole(ctx));
        String answer = llmProvider.generateCompletion(prompt);

        // 5. Add citations and audit trail
        return new RAGResponse(answer, searchResults, intent);
    }

    private String buildPrompt(String question, String context, String role) {
        return """
            You are an AI assistant for iDempiere ERP.
            User role: %s

            Include citations to specific records.
            If you don't have enough information, say so.
            """.formatted(role, context, question);
    }
}

Privacy & Security Considerations:

// CRITICAL: Apply RBAC before sending to LLM
private String buildRAGContext(List<ISearchResult> results, QueryIntent intent) {
    MRole role = MRole.getDefault(ctx, false);

    StringBuilder context = new StringBuilder();
    for (ISearchResult result : results) {

}

Cost Analysis (RAG):

Scenario LLM Provider Cost per Query Cost @ 1K queries/day
Cloud (OpenAI GPT-4) OpenAI API $0.03 $900/month
Cloud (Claude 3.5) Anthropic API $0.015 $450/month
Local (Llama 3 70B) Ollama + GPU $0 €400/month (GPU server)
Hybrid (GPT-4 Turbo) OpenAI API $0.01 $300/month

Recommendation: Start with GPT-4 Turbo for proof-of-concept, migrate to local LLM for production (data privacy)


Opportunity 3: Natural Language Query Interface

What It Is: Allow users to search/query ERP using natural language instead of learning complex SQL or filter syntax.

Example:

Traditional ERP query:
  1. Open Product window
  2. Click "Advanced Search"
  3. Add filter: Category = "Electronics"
  4. Add filter: Price > 100
  5. Add filter: InStock = true
  6. Sort by: Price DESC
  7. Click Search

Natural Language ERP query:
  User types: "expensive electronics we have in stock"
  AI translates to: Category="Electronics" AND Price>100 AND InStock=true ORDER BY Price DESC
  Results displayed immediately

ERP Use Cases:

  1. Sales Rep Finding Products

    Traditional: Navigate menus, know exact product codes
    
    Natural Language:
    - "Show me all blue widgets under €50"
    - "Products similar to what customer ABC usually orders"
    - "Best sellers in the gardening category this month"
    
  2. Manager Analyzing Data

    Traditional: Create custom report, know table names, write SQL
    
    Natural Language:
    - "Total sales by region last quarter"
    - "Customers who haven't ordered in 6 months"
    - "Profit margin trends for product line X"
    
  3. Warehouse Staff Inventory Check

    Traditional: Memorize product codes, navigate multiple screens
    
    Natural Language:
    - "Where is the red paint stored?"
    - "How many units of SKU 12345 do we have?"
    - "Show me items below reorder point"
    

Technical Implementation:

// Natural Language Query Provider
public class NLQueryProvider implements ISearchIndexProvider {

    @Reference
    private ILLMProvider llmProvider;

    @Override
    public List<ISearchResult> getSearchResults(Properties ctx, String searchIndexName,
                                                String query, boolean isAdvanced,
                                                SearchType searchType, String orderBy) {
        // 1. Parse natural language to structured query
        StructuredQuery structured = parseNaturalLanguage(ctx, query, searchIndexName);

        // 2. Execute structured query
        return executeStructuredQuery(ctx, structured);
    }

    private StructuredQuery parseNaturalLanguage(Properties ctx, String nlQuery,
                                                   String searchIndexName) {
        // Get search index schema
        SearchIndexConfig config = SearchIndexConfigBuilder.build(ctx, searchIndexName);
        String schemaDescription = buildSchemaPrompt(config);

        // LLM prompt for query translation
        String prompt = """
            Convert this natural language query to a structured search query.

            Available fields and their types:
            %s

            User query: "%s"

            Output JSON format:
            {
              "filters": [
                {"field": "Category", "operator": "=", "value": "Electronics"},
                {"field": "Price", "operator": ">", "value": 100}
              ],
              "orderBy": "Price DESC",
              "limit": 10
            }
            """.formatted(schemaDescription, nlQuery);

        String jsonResponse = llmProvider.generateCompletion(prompt);
        return parseStructuredQuery(jsonResponse);
    }
}

Example Transformations:

NL: "cheap red flowers"
→ Structured: {
    filters: [
      {field: "Color", op: "=", value: "Red"},
      {field: "Category", op: "=", value: "Flowers"},
      {field: "Price", op: "<", value: 20}
    ],
    orderBy: "Price ASC"
  }

NL: "products similar to what John bought last month"
→ Structured: {
    semanticQuery: "products matching order history for customer John",
    filters: [
      {field: "Customer", op: "=", value: "John"},
      {field: "OrderDate", op: ">", value: "2024-11-01"}
    ],
    useSemanticSimilarity: true
  }

NL: "overdue invoices for customers in Germany"
→ Structured: {
    filters: [
      {field: "IsPaid", op: "=", value: false},
      {field: "DueDate", op: "<", value: "TODAY"},
      {field: "CustomerCountry", op: "=", value: "Germany"}
    ],
    orderBy: "DueDate ASC"
  }

UI Integration:

<!-- Natural Language Search Bar (ZK UI) -->
<div class="nl-search-container">
    <textbox id="nlSearchBox"
             placeholder="Ask me anything... (e.g., 'show expensive products in stock')"
             onOK="onNLSearch()"
             width="100%" />

    <div id="nlSuggestions" visible="false">
        <!-- AI-powered autocomplete suggestions -->
        <button onClick="selectSuggestion('products below reorder point')">
            🔍 Products below reorder point
        </button>
        <button onClick="selectSuggestion('customers with overdue invoices')">
            💰 Customers with overdue invoices
        </button>
    </div>
</div>

<script>
function onNLSearch() {
    String query = nlSearchBox.getValue();

    // Call NLQueryProvider via search index
    List<ISearchResult> results = searchIndexProvider.getSearchResults(
        ctx, "product_idx", query, false, SearchType.NATURAL_LANGUAGE, null
    );

    displayResults(results);
}
</script>

Opportunity 4: Multi-Modal Search (Text + Images + Structured Data)

What It Is: Search across different data types simultaneously - text descriptions, product images, technical specs, etc.

Example:

Traditional: Search products by text description only

Multi-Modal:
  User uploads photo of a chair
  AI finds:
  - Products with similar visual appearance
  - Products in same category (furniture)
  - Products with similar text descriptions
  Results ranked by combined similarity

ERP Use Cases:

  1. Visual Product Search

    Scenario: Customer service rep receives photo from customer
    
    Traditional: Describe photo in words, search by text
    
    Multi-Modal:
    1. Upload photo
    2. AI extracts visual features (color, shape, material)
    3. Searches text descriptions AND image embeddings
    4. Finds matching products even if description incomplete
    
  2. Technical Drawing Search

    Scenario: Engineer looking for similar parts
    
    Traditional: Search by part number or manual keyword entry
    
    Multi-Modal:
    1. Upload CAD drawing or photo of part
    2. AI understands shape, dimensions, features
    3. Finds similar parts across the catalog
    4. Ranks by visual + functional similarity
    
  3. Document Search with Context

    Scenario: Finding contracts or specifications
    
    Traditional: Keyword search in document text
    
    Multi-Modal:
    1. Search query: "contract with payment terms 90 days"
    2. AI searches:
       - Text content (keywords "payment terms", "90 days")
       - Structured metadata (contract type, date, customer)
       - Scanned image content (OCR + visual layout)
    3. Finds relevant contracts even if scanned/non-searchable

Opportunity 5: Personalized & Context-Aware Search

What It Is: Rank search results based on user context (role, history, preferences, location, time).

Example:

Same query: "tools"

Warehouse Manager sees:
  - Inventory management tools
  - Barcode scanners
  - Picking optimization software

Maintenance Technician sees:
  - Repair tools (wrenches, screwdrivers)
  - Diagnostic equipment
  - Spare parts

Sales Rep sees:
  - CRM tools
  - Product catalogs
  - Customer engagement tools

→ Same keyword, different context → different results

ERP Use Cases:

  1. Role-Based Ranking

    -- Traditional: Same results for everyone
    SELECT * FROM M_Product WHERE Name LIKE '%computer%'
    
    -- AI-powered: Personalized ranking
    SELECT * FROM M_Product
    WHERE Name LIKE '%computer%'
    ORDER BY
      CASE
        WHEN AD_Role_ID = 1000 THEN /* IT Manager */
          (Price_High_Weight * 0.2 + Specs_Weight * 0.8)
        WHEN AD_Role_ID = 2000 THEN /* Sales */
          (Price_Low_Weight * 0.5 + Availability_Weight * 0.5)
        ELSE
          Default_Ranking
      END DESC
  2. Purchase History Personalization

    User: "ink cartridges"
    
    Traditional: All ink cartridges, sorted by name
    
    AI-powered:
    1. Check user's printer model (from purchase history)
    2. Filter to compatible cartridges FIRST
    3. Rank by:
       - Previous purchases (user usually buys black, not color)
       - Price preference (user prefers mid-range)
       - Availability (user needs it fast, prioritize in-stock)
    
  3. Seasonal/Temporal Context

    Query: "decorations"
    
    December: Christmas decorations ranked first
    October: Halloween decorations ranked first
    Spring: Garden decorations ranked first
    
    → Same query, different time → different ranking
    

Technical Implementation:

            // Factor 2: Purchase history similarity (25% weight)
            personalScore += calculateHistorySimilarity(result, context.getPurchaseHistory()) * 0.25;

            // Factor 3: Price preference (20% weight)
            personalScore += calculatePricePreference(result, context.getPreferences()) * 0.2;

        });

        // Re-rank by combined score (base relevance + personalization)

Machine Learning Model for Personalization:

# Training data: user interactions with search results
# Features: user role, query, result clicked, purchase made, time spent

import pandas as pd
from sklearn.ensemble import GradientBoostingClassifier

# Load training data
data = pd.read_csv("search_interactions.csv")
# Columns: user_id, role_id, query, result_id, clicked, purchased, time_spent

# Features
X = data[['role_id', 'query_embedding', 'result_embedding',
          'price', 'in_stock', 'purchase_history_match', 'seasonal_score']]

# Label: Did user click/purchase?
y = data['clicked'] * 0.5 + data['purchased'] * 0.5

# Train model
model = GradientBoostingClassifier(n_estimators=100)
model.fit(X, y)

# Save model for use in Java via ONNX or REST API
model.save('personalization_model.pkl')

Deployment:

// Load ML model in OSGi service
@Component
public class PersonalizationModelService {

    private ONNXModel model;

    @Activate
    public void activate() {
        // Load ONNX model
        model = ONNXModel.load("/models/personalization_model.onnx");
    }

    public double predictRelevance(UserContext user, ISearchResult result) {
        // Prepare features
        float[] features = new float[] {
            user.getRoleId(),
            ...
            result.getPrice(),
            result.isInStock() ? 1.0f : 0.0f,
            ...
        };

        // Run inference
        return model.predict(features)[0];
    }
}

Part 3: ERP-Specific AI Opportunities

1. Intelligent Document Processing

Use Case: Automatically index and search scanned documents (invoices, contracts, purchase orders)

// Document AI Provider
public class DocumentAIProvider implements ISearchIndexProvider {

    @Reference
    private IOCRService ocrService; // Tesseract, Google Vision, etc.

    @Reference
    private IDocumentUnderstanding duService; // Extract entities, relationships

    @Override
    public void createIndex(Properties ctx, SearchIndexData data, String trxName) {
        // 1. Get document (PDF, image)
        byte[] documentData = getAttachment(data.getRecordID());

        // 2. OCR if scanned image
        String extractedText = ocrService.extractText(documentData);

        // 3. Understand document structure
        DocumentStructure structure = duService.analyze(extractedText);
        // Extracts: invoice number, dates, line items, total, vendor, etc.

        // 4. Create searchable index with structured metadata
        String sql = """
            INSERT INTO searchindex_documents
            (ad_client_id, ad_table_id, record_id, full_text, entities, metadata)
            VALUES (?, ?, ?, to_tsvector(?), ?::jsonb, ?::jsonb)
            """;

        PreparedStatement ps = DB.prepareStatement(sql, trxName);
        ps.setString(4, extractedText); // Full-text search
        ps.setString(5, new Gson().toJson(structure.getEntities())); // Named entities
        ps.setString(6, new Gson().toJson(structure.getMetadata())); // Structured data
        ps.executeUpdate();
    }
}

Example Queries:

"Find all invoices from vendor ACME over €10,000 from last year"
  → AI extracts: vendor="ACME", amount>10000, date>2024-01-01
  → Searches both text AND structured entities
  → Works even on scanned/OCR'd documents

2. Anomaly Detection in Business Data

Use Case: Automatically flag unusual transactions, orders, or inventory changes

// Anomaly Detection Provider
public class AnomalyDetectionProvider implements ISearchIndexProvider {

    @Reference
    private IAnomalyDetectionModel anomalyModel;

    @Override
    public void createIndex(Properties ctx, SearchIndexData data, String trxName) {
        // 1. Extract features for anomaly detection
        Map<String, Double> features = extractFeatures(data);
        // Example: transaction amount, time of day, vendor history, etc.

        // 2. Calculate anomaly score
        double anomalyScore = anomalyModel.predict(features);
        // Score: 0.0 (normal) to 1.0 (highly anomalous)

        // 3. Store with metadata
        String sql = """
            INSERT INTO searchindex_anomalies
            (ad_client_id, ad_table_id, record_id, anomaly_score, features, flagged)
            VALUES (?, ?, ?, ?, ?::jsonb, ?)
            """;

        ps.setDouble(4, anomalyScore);
        ps.setBoolean(6, anomalyScore > 0.8); // Flag if score > threshold
        ps.executeUpdate();

        // 4. Send alert if anomaly detected
        if (anomalyScore > 0.8) {
            sendAnomalyAlert(ctx, data, anomalyScore);
        }
    }
}

Example Alerts:

"Unusual invoice detected:
 - Amount: €50,000 (10× typical amount for this vendor)
 - Vendor: New supplier (first transaction)
 - Time: 11:47 PM (outside normal business hours)

 Recommendation: Review before approval"

3. Predictive Search & Recommendations

Use Case: Suggest what user will search for next, recommend products proactively

// Predictive Search Provider
public class PredictiveSearchProvider implements ISearchIndexProvider {

    @Reference
    private IRecommendationModel recommendationModel;

    public List<String> predictNextQuery(Properties ctx, String currentQuery) {
        // Based on:
        // - User's search history
        // - Other users with similar patterns
        // - Business context (time, role, recent activities)

        UserContext user = buildUserContext(ctx);
        List<String> suggestions = recommendationModel.predictQueries(user, currentQuery);

        return suggestions;
        // Example: ["red roses"] → suggests ["white roses", "rose vase", "flower delivery"]
    }

    public List<ISearchResult> recommendProducts(Properties ctx, int productId) {
        // Product-to-product recommendations
        // "Customers who viewed this also viewed..."

        // 1. Get embedding for current product
        float[] productEmbedding = getProductEmbedding(productId);

        // 2. Find similar products
        String sql = """
            SELECT ad_table_id, record_id,
                   embedding <=> ?::vector AS distance
            FROM searchindex_vector
            WHERE ad_client_id = ?
              AND record_id != ? -- Exclude current product
            ORDER BY embedding <=> ?::vector
            LIMIT 10
            """;

        // 3. Combine with business rules
        // - Filter out out-of-stock items
        // - Boost frequently purchased together
        // - Apply margin/profitability weighting

        return results;
    }
}
