The Command Based Query provides a powerful, highly flexible search with a range of operators for refining queries. It uses the complete Query Syntax to create more detailed and sophisticated searches than Menu-Assisted or Natural Language queries.
The default website does not provide a stand alone Command Based search form by default. This could easily be implemented using standard Perceptive Enterprise Search search page customization techniques. Alternatively, the query could be entered directly into the Menu Assisted search page.
See the Query Syntax for complete details on the available search operators.
