The problem

Searching a codebase is a relevance problem, not just a string-matching problem.

The index must stay small, incremental, git-aware, and fast enough to sit inside an AI coding workflow.

A single Rust binary indexes filenames, paths, and content into SQLite FTS5, ranks with BM25, updates only changed files, and prunes deletions.

The README reports approximately 10 ms queries on 10K-file codebases after the first index.
