We'd also want to look at using Russian stemming in this separate index. We'd have to figure out how to give the users a frontend where they can choose to search Russian vs English. (Or we could try to auto-detect it? Language auto-detection and then build a separate table?)

I'm happy to do something like this -- it'd be nice to better support our non-English users... I'm not sure what the right way to do it is...

I suppose I could do an easy test with the delta index. Let me away to do that...
