ASK is Centiare's parser function free-form query tool that can be used in conjunction with or as an alternative to the Search Triple query-by-form tool.
Example
Suppose you were interested in displaying all of the Centiare articles where a Latitude attribute between 39 degrees and 40 degrees North has been tagged. The following example ASK query...
<ask> [[City:=*]] [[State Code:=*|State]] [[Zip:=*]] [[Latitude:=>39.0]][[Latitude:=<40.0]][[Latitude:=*|Latitude]] </ask>
...produces this report:
<ask> * State * >39.0Property "Latitude" (as page type) with input value ">39.0" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.<40.0Property "Latitude" (as page type) with input value "" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.Latitude </ask>
Of course, this is just an example, and ASK queries may be written to be as inclusive or restrictive of qualifying attributes as the author wishes.
