Fair point. My personal guess is that Solr's support for regex search
was not up to par at that point. codesearch is not about simple string
searching, but about regex as well, which was long something that wasn't
very performant because it couldn't be indexed efficiently.

The few bits I read up about Solr + regex seem to imply that your
indices somewhat explode in size (because it has to look at more context
than for simple strings), but that may or may not be true anymore.

Kind regards
