Dramatic increase in search speed

I've been worried about the search speed for some time. The removal of the number of results for each individual category was meant to improve things, it didn't.

Yesterday (see previous post) I introduced a system that removed search results which we considered not relevant. As well as improving the search relevancy it reduced - dramatically - the number of search results returned. By accident this has resulted in a huge increase in search speed.

Not all accidents are bad!
