Initialize or re-initialize the semantic code search system.

Loads the embedding model and builds or updates the code index. Use force_reindex=True to rebuild the entire index.

Progress will be reported during indexing.

Search the codebase using semantic similarity.

Use natural language descriptions of code you're looking for:

• "function that handles user authentication"

• "error handling for HTTP requests"

• "database connection initialization"

• "unit tests for the payment service"

Returns ranked code snippets with file locations and relevance scores. Combines vector similarity with keyword search for best results.

Best for: Finding functions/classes by purpose or behavior. Not for: Exact pattern matching or finding all occurrences of a variable. Use Grep for exact patterns; use semantic search to find relevant files first.

Re-index a specific file for search.

Use when a file has been modified but not yet re-indexed, or when you want to force a refresh of a file's embeddings.

Pause the file watcher.

Events that occur while paused are discarded. Use resume_watcher to start watching again.

Resume the file watcher after pausing.

Starts watching for file changes again.

Cancel any running indexing job.

The indexing will stop after the current file completes. Partial results are kept in the index.

Clear all indexed data.

Removes all files and chunks from the index. The index will be empty until reindex is called.

Add paths to exclude from indexing (session-only).

Patterns use glob syntax. Examples:

• "node_modules" - exclude any path containing node_modules

• "*.test.py" - exclude files ending in .test.py

• "vendor/**" - exclude everything under vendor/

Exclusions reset when the server restarts.

Remove paths from the exclusion list.

Reverses the effect of exclude_paths for the specified patterns.

Get comprehensive server status.

Returns server state, watcher status, indexing progress, index statistics, and current exclusion patterns.

Start a full reindex of the codebase.

Runs in the background - use get_status to monitor progress. Use cancel_indexing to abort if needed.
