The twitter search API is pretty flexible, but one of the things I wanted was to increase the number of results fetched.
By default, it returns about 20. The API is accessed through:
http://search.twitter.com/search.json?q=query&rpp=itemsperpage&page=pagenumber
Could have just been me, but I couldn't find the "results per page" (rpp) argument anywhere in the docs.
You can continue through the pages by feeding it new "page" numbers.
Now go nuts, knock yourself out!
