What You'll Need
Set these up before or after installing:

Environment variable: BASE_DIR
Path to LanceDB database directory (defaults to ./lancedb/)

Directory where Transformers.js models are cached (defaults to ./models/)

Environment variable: MODEL_NAME
Maximum file size in bytes (defaults to 104857600 / 100MB)
Environment variable: MAX_FILE_SIZE
Maximum distance threshold for filtering search results. Results with distance greater than this value will be excluded. Lower values mean stricter filtering (e.g., 0.5 for high relevance only)
Environment variable: RAG_MAX_DISTANCE
Grouping mode for quality filtering. 'similar' returns only the most similar group (stops at first distance jump). 'related' includes related groups (stops at second distance jump). Unset means no grouping filter
Environment variable: RAG_GROUPING
Maximum number of files to keep in search results. Results are filtered to include only chunks from the top N best-scoring files. For example, 1 returns only the single best-matching file's chunks. Unset means no file filtering.
Environment variable: RAG_MAX_FILES
