Implement IdeSearchProvider for ctags indexes
I am trying to use Builder for Ruby development and it improved a lot over couple of releases. I believe the syntax parsing is heavily based on ctags.
Now, it looks like latest stable version does support Go to definition with Ruby, however the same symbol cannot be found via search filter (e.g. "c ClassName" or "m method_name"). It looks like there is something missing for indexer to be able to pick up those definitions as they already seem to be loaded in memory somewhere.
I am digging in the codebase but this is quite complex one, unable to find any clue.
