codesearch vs coco-search

codesearch: codesearch is a token-efficient MCP server for AI agents that enables local semantic code search. It integrates with OpenCode, Claude Code and other AI assistants to perform intelligent code searches with minimal token usage, all running locally with no external API calls.; coco-search: CocoSearch is a local-first hybrid semantic code search tool that combines vector similarity and keyword matching via RRF fusion. It uses CocoIndex for indexing, Tree-sitter for syntax-aware chunking, and PostgreSQL with pgvector for storage. It supports 32 languages, 9 grammars, dependency graphs, cross-repo search, and multiple interfaces.
