How do I build semantic code search for my repo?

Start with pip installs: tree-sitter, sentence-transformers, chromadb. Chunk via Tree-sitter or regex, embed, store in Chroma. Query embeds match vectors—done in 100 lines.

Best embedding models for code search?

`all-MiniLM-L6-v2` for speed. `codebert-base` or `e5-large` for accuracy. Fine-tune on your codebase for 20-30% lift.

Will semantic code search replace my IDE?

Nah, augments it. IDEs handle edits; this maps the unknown. Pair with Cursor or Copilot—unbeatable.
