With Mayflower search, there was the possibility to search for a term and exclude all files in a category. This helped when categorizing images at Commons. Sample: "Tree -Category:Trees" http://toolserver.org/~tangotango/mayflower/search.php?q=Tree&ic=&ec=Trees&ft=any&sc=gt&sv=&ds=&t=n&z=12&a=3 (broken) It would be nice if this was possible with the standard search at Commons (possibly with Lucene). *Mayflower search hasn't been updated and is broken for some time. *A current workaround is to compare the list of results from search with the list from categories. *[[Bugzilla:21317]] might be related to this.
"Tree -incategory:Trees" However, this has limitations, most notably it searches only the category itself, not the whole subcategory tree (therefore it does not do anything useful in this specific example; try e.g. http://commons.wikimedia.org/w/index.php?title=Special%3ASearch&search=Su-22+-incategory%3A%22Sukhoi+Su-22%22). But that would be (AFAICT/IMHO) practically an impossible task to do, anyway.
Thanks. It seems to work when using "Su-22" -incategory:"Sukhoi Su-22" instead of Su-22 -incategory:"Sukhoi Su-22" Obviously, sometimes subcategories should be checked too, but I don't think Mayflower did that either. One had to list each one separately.
/Search result page format/ (1) To avoid that I forget about this, when searching for "Su-22", it might help if there was a link next the categories to exclude results from this category, e.g. next to the category "Sukhoi Su-22", the link would search for "Su-22" -incategory:"Sukhoi Su-22" The link could be titled something like "exclude results from this category". (2) This might even work recursively. When continuing with "Su-22" -incategory:"Sukhoi Su-22" one could exlude further categories that get listed.

This CirrusSearch query on Commons supports this behaviour: https://commons.wikimedia.org/w/index.php?title=Special%3ASearch&profile=default&search=Tree+-incategory%3A%22Trees%22&fulltext=Search As we're in the process of migrating from Lucene to CirrusSearch, I'm marking this bug as RESOLVED WONTFIX.
