## Collection Management
| Tool | Description |
|------|-------------|
| `create_collection` | Create collection with specified distance metric (Cosine/Euclid/Dot) |
| `list_collections` | List all collections |
| `get_collection_info` | Get collection details and statistics |
| `delete_collection` | Delete collection and all documents |
## Document Operations
| Tool | Description |
|------|-------------|
| `add_documents` | Add documents with automatic embedding (supports string/number IDs, metadata) |
| `semantic_search` | Natural language search with optional metadata filtering |
| `hybrid_search` | Hybrid search combining semantic and keyword (BM25) search with RRF |
| `delete_documents` | Delete specific documents by ID |
## Code Vectorization
| Tool | Description |
|------|-------------|
| `index_codebase` | Index a codebase for semantic code search with AST-aware chunking |
| `search_code` | Search indexed codebase using natural language queries |
| `reindex_changes` | Incrementally re-index only changed files (detects added/modified/deleted) |
| `get_index_status` | Get indexing status and statistics for a codebase |
| `clear_index` | Delete all indexed data for a codebase |
## Search Parameters
### `rerank` — Result Reranking
Reorder search results based on git metadata signals.
**For `semantic_search` / `hybrid_search` (analytics):**
| Preset | Use Case | Signals |
|--------|----------|---------|
| `relevance` | Default semantic similarity | similarity only |
| `techDebt` | Find legacy problematic code | age + churn + bugFix + volatility |
| `hotspots` | Bug hunting | chunkChurn + chunkRelativeChurn + burstActivity + bugFix + volatility |
| `codeReview` | Review recent changes | recency + burstActivity + density + chunkChurn |
| `onboarding` | Entry points for new devs | documentation + stability |
| `securityAudit` | Old code in critical paths | age + pathRisk + bugFix + ownership + volatility |
| `refactoring` | Refactoring candidates | chunkChurn + relativeChurnNorm + chunkSize + volatility + bugFix + age |
| `ownership` | Knowledge transfer | ownership + knowledgeSilo (flags single-author code) |
| `impactAnalysis` | Dependency analysis | imports count |
**For `search_code` (practical development):**
| Preset | Use Case | Boost |
|--------|----------|-------|
| `relevance` | Default semantic similarity | — |
| `recent` | Find recently modified code | low ageDays |
| `stable` | Find stable implementation examples | low commitCount |
**Custom weights:**
```json
{ "custom": { "similarity": 0.7, "recency": 0.3 } }
```
Available weight keys: `similarity`, `recency`, `stability`, `churn`, `age`, `ownership`, `chunkSize`, `documentation`, `imports`, `bugFix`, `volatility`, `density`, `chunkChurn`, `relativeChurnNorm`, `burstActivity`, `pathRisk`, `knowledgeSilo`, `chunkRelativeChurn`
### `metaOnly` — Metadata Only Response
For `semantic_search` / `hybrid_search` only. Returns metadata without content:
```json
{
"score": 0.87,
"relativePath": "src/auth/login.ts",
"startLine": 45,
"endLine": 89,
"language": "typescript",
"chunkType": "function",
"name": "handleLogin",
"imports": ["express", "jsonwebtoken", "./utils"],
"git": { "ageDays": 5, "commitCount": 12, "dominantAuthor": "alice" }
}
```
`imports` contains file-level imports (inherited by all chunks from that file). Used by `impactAnalysis` reranking to boost files with many dependencies.
Use for file discovery, analytics, or reducing response size.
