Re[4]: MySQL FullText improvements in V4.0

Honestly I am not sure how it would scale, it has worked well in my use with several thousand very large documents (a couple million rows in the index table). You certainly couldn't use this to develop an internet search engine... I had never heard of MySQL not using keys in an OR type of query,
