BM25 has been sufficient for my needs. I typically need to refer to codebases of existing tools as referential sources (istio, envoy, oauth2-proxy, tantivy index etc) so I just clone those repos, index them and search away. Built a cli and mcp tool for this workflow. https://github.com/rhobimd-oss/shebe https://github.com/rhobimd-oss/shebe One area where BM25 particularly shines is the refactoring workflow: let's say you want to upgrade your istio installation from 1.28 to 1.29 and maybe in 1.29 the authorizationpolicy crd has a breaking change in one of it's properties. BM25 allows you to efficiently enumerate all code locations in your codebase that need to change and then you can set the cli coders off using this list. Grep and LSP can still perform this enumeration but they have shortcomings.
