Hello everyone,

In the Intranet application I've been building over the past 9 months, I have 
developed quite a beast of a search.  I've asked for help here in the past on 
performance tuning it, and have come to the conclusion that I've gotten it as 
tweaked as I can without seeking the counsel of a shamen.

What I'm looking at doing is improving in-page performance. In a nutshell, how 
expensive is it to create a temporary table?  I'd like to do something like:

CREATE TEMP TABLE SearchResults AS [......];

I could then do some queries against the temporary table without having to 
regenerate the results every time I want to show a "Page 299 of 500" toolbar.

Would I be better off just sucking this data into an in-memory data structure, 
or can I use a temp table as an easy-to-use alternative?
