Google Code Search-like source code indexer and visualizer [closed]

Question

I'm looking for a way to search through our subversion repository or just packaged source code.

Are there any downloadable servers/tools like Google Code Search to index source code (preferable with support of version control systems like svn) and allow us to search in it?

Is there any tool that will index documents too?

Answer 1

FishEye or OpenGrok possibly.

There are many tools that will index documents.

Answer 2

I believe the source code for Google Search is available here. It's implemented in Go https://code.google.com/p/codesearch/
