svn - Searching subversion history (full text)

Question

Is there a way to perform a full text search of a subversion repository, including all the history?

For example, I've written a feature that I used somewhere, but then it wasn't needed, so I svn rm'd the files, but now I need to find it again to use it for something else. The svn log probably says something like "removed unused stuff", and there's loads of checkins like that.

Edit 2016-04-15: Please note that what is asked here by the term "full text search", is to search the actual diffs of the commit history, and not filenames and/or commit messages. I'm pointing this out because the author's phrasing above does not reflect that very well - since in his example he might as well be only looking for a filename and/or commit message. Hence a lot of the svn log answers and comments.

git svn clone <svn url>

git log -G<some regex>
