I found the answer. What I was looking for was stemming, or "word stemming". This takes words like dancing, and breaks it down to it's root. It'll look for dancer, dance, etc.
This is where I read about it:
http://blogs.msdn.com/miketag/archive/2006/12/27/moss-search-word-stemming-part-2.aspxHe's quite good, what I could add to that is, if you're using a webservice to query your search server, use the following tags:
trueleStemming>
If you'd like to remove the noise words, please use:
true</IgnoreAllNoiseQuery>
It took a lot of searching, but I needed the proper word to search by first.
Have fun!
