Wikipedia:Tip of the day/October 17
AutoWikiBrowser is a semi-automatic page loader and editor designed for working on large batches of Wikipedia pages. One of its tools, the database scanner, lets you do exhaustive searches of the encyclopedia's content. It can search article titles and article contents.
It will find absolutely every occurrence of the search string, and return the names of all the articles that contain it. The tool supports regex, and scripts so you have unlimited possibilities for search criteria.
The tool works off-line, directly on a copy of the Wikipedia database that you have downloaded.
