Help:Special page "Ask"
On the top of the page there are two text area fields. The first one, titled 'Query', is meant for the portion of the query for selecting pages. The second one, titled 'Additional data to display', is meant to hold the set of properties that are displayed for each queried page - see the help page on displaying information. Each property should be prepended with a question mark, just as is done in regular #ask queries. As of Semantic MediaWiki 1.5.2, this field has autocompletion on property names, meaning that you can start typing the beginning of a property name, and a set of completions will show up. You can also just type a question mark, and you will see the list of all properties defined on the wiki at once.
As of Semantic MediaWiki 1.5.0, additional controls are shown under the text fields, which allow the user to pass parameters to the query that give extra control over how the data is displayed. The controls shown change according to the result format selected, as different formats support different parameters.
Running the query
You can run the query by hitting the 'find results' button in the lower left corner of the page, after which the results will be shown.
Downloading the results
Semantic MediaWiki 2.4.0 introduced quick download links shown above the queried results to the right allowing to download them immediately in JSON, CSV, RSS and RDF.1 See the screenshot on this page.

Results of a query displayed on this special page are not parsed further. This means that results for properties of datatype "Text" containing links will be displayed as-is, i.e. links like SMW Project within the data value will be displayed as [[Help:SMW Project|SMW Project]] even if this configuration parameter is enabled.
