I'm using MySQL for an information retrieval application where word
occurrences are indexed. It seems that performance is not as good as
I would expect (it seems nearly linear with the number of rows).
Any advice would be welcome. I'll lay out a lot of detail.
Some details follow. The basic
It sounds like you are trying to do full text searching, but you
