Show HN: Hybrid Semantic Grep for Claude Code (github.com)

NextPlaid has introduced ColGREP, a powerful semantic code search tool designed for local use. Built on a multi-vector search engine, ColGREP enables developers to perform searches using a combination of regex filtering and semantic ranking without any external server or API dependencies. This means that sensitive code never leaves a user's machine, ensuring privacy while providing an efficient way to search through codebases. The easy installation and setup (including indexing capabilities) make it accessible for developers looking to enhance their productivity within their terminal or coding agents. The significance of ColGREP lies in its innovative multi-vector embedding approach, which retains around 300 embeddings per code document, allowing for more nuanced and accurate searches than traditional single-embedding methods. It leverages structured representations of code to optimize search results, effectively accommodating the complexities inherent in code like function names, parameters, and dependencies. The integration of lightweight Rust binaries ensures low memory usage and incremental updates, positioning ColGREP as a robust tool in the AI/ML community that addresses a common pain point in code search and retrieval.
