Re: Search function on this site

It does not use Sphinx, I have some sites that do and it seems to work well, but its still no google 
It uses the custom search index option, can't remember which index but it should be the largest size. In 2.0 we should really consider removing the other custom index sizes since I don't want to answer the question of why one is better then the other and most of the reason why there are options is more due to dated server/hardware limitations that no longer apply.
