We have a huge, old, horrible codebase that makes it nearly impossible to find things when you need it. We're working on improving it, sure... but I often find myself doing massive recursive greps to search through the contents of files to find where things are used.
Is there a tool I can use to build a fulltext index of text files in a directory and then query that from the command-line?
Prefer something that can be run in user-space and doesn't need a daemon. We have many users on our dev server, so I want something that I can search through my instance of the codebase.
