I've gotten good usage out of a structured search tool (not mine, by someone else here) called Tilth:

It combines search with tree sitter grammars so the results can annotate usage vs definitions, cite line number ranges, inline the actual definition if it's short, etc. Not as precise as LSP but simple (no daemon), human readable, and in many cases works without configuration.
