MediaWiki code search is a fully free software tool that lets you easily search through all of MediaWiki core, extensions, and skins that are hosted on Gerrit. You can limit your search to specific repositories, or types of repositories too. Regular expressions are supported in both the search string, and when filtering by path.

This is really awesome, Kunal! Great work! Thanks for filling a gap for us :)
