Take a look at ferret as a starting point. If you need more "oomph" you can move to either sphinx or solr. The "Advanced Rails Recipes" book has examples of all 3.

Even after rebuilding and updating the indicies several times, fulltext searching doesn't manage to search the entire body of text, only the first few lines. Investigation shows that the Xapain google groups list is almost pure spam and isn't active at all. I guess I've chosen a duff technology to use, so I'll need to switch. Can anyone suggest the current favorite for fulltext searching? I don't really care about the spelling correction or highlighting of search terms (it interferes with my caching), just a simple search.
