+
+## Query Syntax for AI Agents
+
+### Project Targeting
+```bash
+# Single project, default version
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+authentication'
+
+# Specific version
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs/latest+authentication'
+
+# Multiple projects
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+project:django+api'
+
+# Include subprojects
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=subprojects:docs/latest+configuration'
+```
+
+### Advanced Search Operators
+```bash
+# Exact phrase (most useful for precise matches)
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+"configuration+file"'
+
+# Prefix search (find variations)
+# matches: config, configuration, configure
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+config*'
+
+# Fuzzy search (handle typos)
+# finds "authentication"
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+authenitcation~2'
+
+# Proximity search (words near each other)
+# "build" and "docker" within 3 words
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+"build+docker"~3'
+```
+
+## Common AI Agent Patterns
+
+### 1. Find Documentation About Specific Topic
+```bash
+# Get documentation pages about a specific topic
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+authentication+middleware&page_size=10' | jq
+
+# Extract just titles and URLs
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+authentication&page_size=10' | \
+  jq -r '.results[] | "\(.title): \(.domain)\(.path)"'
+```
+
+### 2. Extract Content from Search Results
+```bash
+# Extract all text content for LLM context
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:requests+authentication' | \
+  jq -r '.results[] | "## \(.title)\nSource: \(.domain)\(.path)\n\n\(.blocks[] | "### \(.title)\n\(.content)\n")"'
+
+# Get just block content
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:requests+authentication' | \
+  jq -r '.results[].blocks[].content'
+```
+
+### 3. Search Multiple Related Projects
+```bash
+# Search across multiple related projects (Django ecosystem)
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+project:django-rest-framework+project:celery+task+queue&page_size=50' | jq
+```
+
+### 4. Get All Results (Pagination)
+```bash
+# Fetch first page
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:sphinx+extension&page_size=50&page=1' | jq
+
+# Fetch next page (use the 'next' URL from response)
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:sphinx+extension&page_size=50&page=2' | jq
+
+# Check if there are more pages
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:sphinx+extension&page_size=50' | jq '.next'
+```
+
+### 5. Find Code Examples
+```bash
+# Search for pages likely containing code examples
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:flask+authentication+code*+example*+tutorial*+guide*&page_size=20' | \
+  jq -r '.results[] | select(.title | test("example|tutorial|guide|howto"; "i")) | "\(.domain)\(.path)"'
+```
+
+### 6. Check Documentation Coverage
+```bash
+# Check how many documentation pages exist for each topic
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+authentication&page_size=1' | jq '.count'
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+database&page_size=1' | jq '.count'
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+caching&page_size=1' | jq '.count'
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+deployment&page_size=1' | jq '.count'
+```
+
+## Quick Reference for AI Agents
+
+```bash
+# Basic search
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:PROJECT-SLUG+SEARCH+TERMS'
+
+# Specific version
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:PROJECT-SLUG/latest+SEARCH+TERMS'
+
+# Include subprojects
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=subprojects:PROJECT-SLUG+SEARCH+TERMS'
+
+# Exact phrase
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:PROJECT-SLUG+"exact+phrase"'
+
+# Fuzzy search (typo tolerance)
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:PROJECT-SLUG+word~2'
+
+# Prefix search
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:PROJECT-SLUG+prefix*'
+```
+
+## Response Parsing with jq
+
+```bash
+# Get just URLs
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+api' | \
+  jq -r '.results[] | "\(.domain)\(.path)"'
+
+# Get titles and URLs
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+api' | \
+  jq -r '.results[] | "\(.title): \(.domain)\(.path)"'
+
+# Extract all block content
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+api' | \
+  jq -r '.results[].blocks[].content'
+
+# Check which projects were actually searched
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:docs+api' | \
+  jq '.projects[] | {slug: .slug, versions: [.versions[].slug]}'
+```
+
+## Common Projects to Search
+
+```bash
+# Popular Python projects
+docs           # Python official docs
+django         # Django
+flask          # Flask
+requests       # Requests

+
+# Example usage
+curl -s 'https://app.readthedocs.org/api/v3/search/?q=project:django+models' | jq
