Searching

Search methods

// Hybrid search (default: semantic + BM25 via RRF)
const results = await indexer.search(query, options?);

// Semantic only
const results = await indexer.searchSemantic(query, options?);

// Lexical / BM25 only
const results = await indexer.searchLexical(query, options?);

// Hybrid + graph-context expansion
const results = await indexer.searchWithContext(query, options?);

SearchOptions

{
  limit?: number,                          // default: 10
  language?: Language | Language[],        // filter by language
  types?: ChunkType[],                     // filter by chunk type
  filePath?: string,                       // path filter (glob patterns supported)
  hybrid?: boolean,                        // default: true when embeddings available
  minScore?: number,                       // minimum score threshold (0–1)
  rerank?: boolean,                        // apply reranking after RRF; default: true when rerankingFunction set
  rrfK?: number,                           // RRF rank constant k; default: 45 (tuned for code retrieval)
}

SearchWithContextOptions

Extends SearchOptions:

{
  graphDepth?: number,                     // BFS hops to expand — default: 1
  graphRelationTypes?: RelationshipType[], // edge types to follow — default: all
  contextScoreDiscount?: number,           // score multiplier for neighbour chunks — default: 0.7
}

SearchResult

{
  chunk: CodeChunk,
  score: number,                           // higher = more relevant
  matchType: 'semantic' | 'lexical' | 'hybrid',
