Implement Search Filtering for Remote Repositories

[amondnet]

Overview

Add metadata-based filtering to search queries for remote repositories.

Tasks

• Update semanticSearch() to generate filter expressions
• Add filterExpr for remote repository searches
• Test filter accuracy (correct version filtering)
• Optimize filter performance
• Add integration tests
• Document filter behavior

Acceptance Criteria

• Search only returns results from specified version
• Filter expression correctly matches metadata
• No performance degradation vs unfiltered search
• Works with both Qdrant and Milvus
• Integration tests verify filtering

Implementation Details

// When searching remote repository
const filterExpr = 'metadata["repository"] == "github://owner/repo@v1.0"'

await hybridSearch(collectionName, searchRequests, {
  filterExpr,
  limit: topK
})

Dependencies

• Depends on: Update Collection Naming for Versioned Repositories #28 (Collection Naming), Extend VectorDocument Metadata Schema for Remote Repositories #29 (Metadata Schema)
• Blocks: #TBD (Multi-Repository Search)

Estimated Effort

5-6 days
