I'm working on a patch that limits the number of search results to
around 50 when doing search-as-you-type. At the moment you can search
for "gno" and get 900 results, which takes a long time to refine and
then add as widgets. The user clearly doesn't want to see scroll
through 900 results, so we can just show the top few pages and then a
simple label saying more are available -- typically the user is
entering the next character anyway and the list never gets shown.
Limiting to 50 results turns the search-as-you-type back to being
responsive for all searches.
