allow wildcards in filters

[cbarraford]

It would be nice to allow wildcards ("*") when filtering. Or even better regex?

Yeah, that would be nice. There are two different UX mechanisms at play, real-time filtering and auto-completion suggestions. These are similar, but different. It is possible to do both (Graphite does in the web UI), but it can be confusing (Try doing a wildcard in Graphite, you have to let it give you autocomplete results, but then ignore them, press escape, and and type a * or whatever).

I'd prefer realtime filtering over the current autocomplete feature. Generally, I know enough about what I'm looking for that the suggestions aren't helpful, but thats just my preference.

We tried playing around with more powerful filtering (wildcards, fuzzy searching, etc.) before but performance sucked. I'll gladly accept any pull requests that don't hinder performance though!
