Remarks
Runs a query with the specified constraint. This query is requested by the filter attached to this adapter.
The query is provided by a android.widget.FilterQueryProvider. If no provider is specified, the current cursor is not filtered and returned.
After this method returns the resulting cursor is passed to #changeCursor(Cursor) and the previous cursor is closed.
This method is always executed on a background thread, not on the application's main thread (or UI thread.)
Contract: when constraint is null or empty, the original results, prior to any filtering, must be returned.
