I don't know where to make recommendations or file a "suggestion" but really, is someone working on the Help file within Dev Studio? I searched for "sort group" and the page with the highest rank was (drum roll):

MIRR: Calculating the Modified Internal Return Rate

I'd really love to see the search feature work properly, as it happens all the time. Where does one file/log this type of suggestion?

agreed.
but i also an sympathetic to the fact that its a question of indexing everything ever written since Gerry became Gerry, to get Googly search results. And thats a tall order... expensive... imho too much to ask.
So, searching on the online system (see the 2 links on this very page, above right?) is probably where the indexing effort is gonna go.
