The problem with each full text indexing technology is they have their own things of what they do or not. Everytime you switch, you end up loosing some of the existing functionalities and benefit of new ones. And, in some cases, most of them are useless. The one I have right now is built in the SQL Server engine and I just need to see if I can enhance in that direction.
