Wishlist Item: Better search

I don't know how many times I've had this happen - I search for some obscure programming topic, only to get 43 results, 42 of which are other people asking the same question on some newsgroup or forum without getting an answer.Then I have to manually sift through the 43 results to find an answer. Suggestion to Google Groups : Advanced Search: add an option to exclude threads with only one message.
