The search qualifiers shown in the Filter Display Tab on Search View Screens produce the Filter tab or the search criteria section of the object's search screen, as shown in the following image. Notice the section titles and the vertical display order of the search qualifiers. Also notice that the invisible qualifiers are not displayed.

When list fields that are associated with a lookup table are added as search qualifiers, the fields appear as combo list boxes to allow for multiple selections.
