The steps include:
For example, the "Matching Descriptions" side might say "Greater Than" and in the "Values" (right hand) side of the table is ">", the corresponding SQL symbol. If you are unfamiliar with SQL, use the default values.
You may not want to allow search terms to be entered. Another type of search pull-down list includes set values. For example you might have a column named Status. In the Matching values table you could have Active, Inactive, Pending. The corresponding SQL terms might be ='A', ='I', ='P'. Where A, I and P are the actual values in the table which determine a user's status.
Now press the Add result List tab.
