Google's English word stemming is smart. I'm very jealous of it and want one too. If you, for example, search for set up ssh key then it perfectly finds "setting up ssh key" too. You can tell by how Google is bold-highlighting the words. Clever! I want such stemming too. I wonder if there's anything already done in Zope that I can use or if I have to write something myself.
Seeing how powerful this really is, I'm now more inspired to sort it out with my ZCatalog.
