How to add filters to Search for Items screen

Summary:

Searching on items to add to a PO returns multiple records (as item is assigned to 3 inv orgs plus master). Guidance is to use filters to pick the correct record, however there are no filters. I cant see anyway in Visual Builder to add any fields to filter by either. Plse can someone advise how to get filters visible.
