If you have a Search/Retrieval configuration that you want to have Sort by more than one column do the following.
1. Open the configuration pad in Notepad.
2. Search for the option value <SORT_FIELD>
3. Normally there is one value in the section that looks like this: <SORT_FIELD>FIELD1</SORT_FIELD>
4. Add the fields that you want to search by as the database columns like this: <SORT_FIELD>[FIELD1],[FIELD2]</SORT_FIELD>
