ColGrep pairs code-search filters with semantic matching

ColGrep combines regex and file filters with semantic matching—searching by meaning—according to Weaviate Podcast. The podcast says LightOn trained models small enough to index a codebase locally on a laptop, including a 70-million-parameter code retriever it says outperformed everything up to 300 million parameters. It credits the ColGrep approach with fewer repeat queries, fewer tokens spent on search and better answers on the hardest queries.
