Grep vs Ranked File Retrieval: What Actually Works

What grep does well

• Exact string lookup
• Fast local search when you already know the symbol, endpoint, or phrase
• Low-friction validation after you already have a hypothesis

Where grep starts to break down

• You do not know the symbol yet.
• The task spans validation, middleware, and tests rather than one exact string match.
• The repo is large enough that raw matches still leave too much manual triage.

What ranked retrieval adds

Ranked retrieval turns the task itself into the retrieval input. Instead of returning all matches, it returns the files most likely to matter first.

That does not replace exact search. It improves the order in which you inspect the repository when the right starting point is not obvious.

A useful rule of thumb

Use grep when you already know what to search for. Use repository-aware ranking when the first problem is figuring out where the task actually lives.
