Using the SE search tool I searched for 'wavelets', and got one set of questions, then I searched for 'wavelet' and got an overlapping set. Then I searched for 'wavelet*' and got another set. I didn't realise that searching was precise enough to distinguish between singulars and plurals, or that you could try an asterisk wild-card. Where can I find this information, say beginner-level ninja search tips, rather than the super ninja search tips (which I've seen)?

  • do an empty search for search tips... The general search behaviour is described before the super ninja options – rm -rf Nov 29 '12 at 17:35
  • No mention of singular/plural matching or wildcard matching (if that's available outside url fields), though...? Oh, well. – cormullion Nov 29 '12 at 18:01

    At the very beginning, it says: apples oranges … will return any questions or answers containing "apples" or "oranges". Note the quotes, so it's an exact string match. I know, it's a bit annoying. Also, if your word happens to be a top 10 tag, it will automatically search for the tag and not the word. For the longest time, I couldn't find this question with the search "compilable functions", despite it being in the title. It was because it didn't have the functions tag (which is a top 10 tag). I fixed it by adding the tag to the Q. – rm -rf Nov 29 '12 at 18:10

Do an empty search, and there will be a link Advanced Search Tips that opens in-place (hence the lack of link here). I've copied the content of that help below. More help on advanced search in the Help Center's search-specific section.
