hybrid_search
Find relevant code by blending semantic vector search with knowledge graph proximity, returning ranked code chunks instead of entire files.
Instructions
Semantic vector search re-ranked by knowledge graph proximity.
Combines vector similarity (cosine) with structural graph proximity
(BFS distance from query-matched graph nodes). The final score is:
score = alpha * vector_score + (1 - alpha) * graph_score
Both vector and graph scores are normalised to [0, 1] before blending.
Requires both index_codebase and index_graph to have been run.
Args:
query: Natural language description of what you're looking for.
path: Absolute path to the codebase root directory.
top_k: Number of results to return (default 8, max 20).
alpha: Weight of vector score vs graph score (0.0 = graph only,
1.0 = vector only, default 0.6).
min_score: Minimum blended score threshold (default 0.0).
Returns:
Formatted list of code chunks ranked by blended score.
