CocoSearch

概要

CocoSearch is a local-first, privacy-focused hybrid semantic code search tool. It indexes codebases using Tree-sitter for syntax-aware chunking and symbol extraction, stores data in PostgreSQL with pgvector embeddings generated by Ollama, and retrieves results through Reciprocal Rank Fusion of cosine similarity and keyword matching. Supporting over 30 languages, it offers multiple interfaces including a CLI, WEB dashboard, interactive REPL, and an MCP server, ensuring all operations, including an optional AI chat feature, run entirely on your machine without external APIs.

• 0 GitHub stars
• Symbol filtering to narrow results by type (function, class) and name (glob patterns)
• Web AI Chat powered by Claude Agent SDK for interactive codebase questioning
• Context expansion using Tree-sitter AST traversal to retrieve complete code units (e.g., full functions or classes)
• Two-level LRU query caching for faster repeated searches and paraphrased queries
• Hybrid search combining semantic similarity and keyword matching via Reciprocal Rank Fusion
