Description Nik Everett 2013-10-01 00:56:46 UTC 
CirrusSearch doesn't stem aliases to alias - just "aliase" which isn't right.
Comment 1 Nik Everett 2013-10-01 01:59:06 UTC 
Looks like I can fix this by switching the porter stemmer with the kstemmer.  I'll do some more research.
Comment 2 Nik Everett 2013-10-01 13:50:29 UTC 
So the problem is that the porter stemmer which we use right now stems "alias" to "alia" and "aliases" to "alias".  They really need to stem to the same place.

I'm going to switch us to the kstemmer.  It was designed as an improvement on the porter stemmer and in my somewhat limited testing it seems better.
