Faceted search

The Faceted Search of Semantic MediaWiki provides users with a simple interface to quickly narrow down query results from a condition with the help of faceted views created from dependent properties and categories.

Use category:?, property:?, or concept:? to find available categories, properties, or concepts to build a condition set
Use the #ask syntax to describe a condition (e.g. [[Category:Foo]])
Use "OR", "AND", or other query expressions to create complex conditions
Expressions like in: or phrase: can be used for full-text matches or unstructured searches, if the selected query engine supports those expressions
