How do I build semantic code search for my Python repo?

Grab langchain, chromadb. Chunk files, embed with OpenAI or HF, store in Chroma. Query natural language for top matches.

What's the cheapest way to run semantic code search?

Ditch OpenAI. Use sentence-transformers locally. No API bills, keeps code private.

Yes—adapt loaders for JS, Go. Splitters handle langs with tweaks.

Semantic search crushes grep for natural queries, but reindex often or it's useless. 𝕏
OpenAI embeddings shine—until costs and privacy bite. Go local with Hugging Face. 𝕏
Not a codebase cure-all; pair with docs and diagrams for real wins. 𝕏
