Overview ¶
Package search implements the SQLite search store for Cortex.
It provides FTS5-based full-text search with BM25 ranking, topic key direct lookup, RRF fusion for hybrid search, and snippet extraction. The store implements the domain.SearchRepository interface.

Types ¶
type GraphEdgeProvider ¶ added in v1.0.0
type GraphEdgeProvider interface {
GetEdgesValidAt(ctx context.Context, obsID int64, at time.Time) ([]*domain.Edge, error)
GetEdgesForObservation(ctx context.Context, obsID int64) ([]*domain.Edge, error)
}
Store implements the SQLite search store. It provides FTS5-based full-text search with advanced features. GraphEdgeProvider is an optional interface for temporal edge filtering. When set, graph neighbor expansion respects temporal validity.
type Store ¶
type Store struct {
Graph GraphEdgeProvider // Optional; enables temporal-aware graph expansion
// contains filtered or unexported fields
}
Store implements FTS5-based search for Cortex.
func (*Store) GetSnippet ¶
func (s *Store) GetSnippet(ctx context.Context, query string, content string, maxLength int) (string, error)
GetSnippet extracts a snippet from the content that matches the query. It uses FTS5's snippet() function to highlight matching terms.
func (*Store) Search ¶
func (s *Store) Search(ctx context.Context, query string, opts domain.SearchOptions) ([]*domain.SearchResult, error)
Search performs a full-text search with the given query and options. It supports:
- FTS5 keyword search with BM25 ranking
- Topic key direct lookup (queries containing '/')
- RRF fusion for combining topic key and keyword results
- Snippet extraction using FTS5 snippet() function
- Column weighting (content 2x title)
Returns search results ordered by relevance (rank).
