The page you have open when you start the DataAssist wizard is the results page.
Before you open the DataAssist wizard, you need to create the results page.
For the results page, you need to add a recordset that you will be filtering, then add the results display using a repeat region to loop through the returned records.
with this results page open, Start the DataAssist search wizard to set up how you would like to filter the recordset that was applied to the results page.
