Extension:Multi-Category Search

Description
Fast and simple extension, that lists pages included in several specified categories at once. By default, user can specify up to 5 such categories, and optionally up to 3 categories to exclude from search. The maximum number of categories is set in two corresponding variables in source code, so you can easily change it at any time.

Purpose and usage
The extension is indispensable if you need, for example, to find all articles about american comedy movies released in 1990 at your wiki. Then you go to page Special:MultiCategorySearch, specify three categories: "USA films", "Comedy films" and "1990 films", and click on search button. That's it - you get the list of movies.
