I often find that the Did You Know feature at the top of search results seems to simply be suggesting similar words from a dictionary, but often they are suggestions that mislead you to think there are more results there. For example, search for "haiku" and it will ask you if you meant "haikyu," but if you click on that, you get 0 results. These sorts of suggestions should be screened out, so only searches with actual results are suggested.
