I've been doing some work on using MSCMS2002 and have had to look at ways to implement search (by default it doesn't have it and requires that you buy a much expensive Sharepoint license) well, I revisited the nLucene project - this had stalled for a while but looks like it's back in development. Interestingly, one of the contributors seems to be Scott W.  - so I wouldn't be surprised if this became integrated with .TEXT in the near future... Anyway, take a look, it does seem incredibly cool and it would seem to benefit from the tons of development already exisitng for the Jakarta-Lucene Java version, even stating that the Java docs also apply to this version!

UPDATE: As Ryan Rinaldi pointed out in the comments,.TEXT 0.96 does have Lucene.NET (the new name for nLucene) already integrated, I was having a poke around the code today and it's pretty sweet. I reall recommend you check it out if you need a simple to implement, quick search engine for your site! Oh, and the next version of .TEXT will have an awesome search engine!
