What are some good code searching web interfaces?

Question

I'm looking for a good web framework/plugin/what have you that greps over a specific codebase.

I've done many searches for something like this including on GitHub and Google code and haven't found what I'm looking for...

Specifically I would like something that can index my code and present a Web UI to search over said codebase for class names, function names or just free text and regexes.

Ideally I could run the indexers at set intervals with cron and maybe the same script could even refresh the code from Git automatically before re-indexing, presenting an always fresh view of my code in the same Web UI.

Phabricator offers code browsing but no code search as far as I can tell.

This should also allow to browser code from the search results.

Are there open source options for doing this?

Answer 1

Krugle for Git and github may be worth a look.

Answer 2

If you have access to Java, I've had some luck using lucene to index source code.
