Help:Semantic search
Special:Ask is a special page that allows for more precise searching than the search bar. It is a powerful tool. Using it requires some special knowledge, however, which this article aims to provide.
The interface
The Condition field is where readers can type their queries. The Printout selection field is used to specify what information should be displayed about each page. It will not be covered here.
The combo box directly under Options specifies how the information is presented. For the purposes of this article, the default of "Broad table" will suffice.
The Find results button is used to run the search.
Categories
The following query finds all pages under the software category Daemons and its subcategories:
[[Category:Daemons]]
Multiple queries can be separated by spaces. When multiple queries are specified, only pages that match all of them are displayed:
[[Category:Daemons]] [[Category:Filesystems]]
This is especially useful for hardware pages. The following matches all HP devices that are based on the AMD64 architecture:
[[Category:HP]] [[Category:AMD64]]
