Search qualifiers appear as criteria on the Custom Search page to allow the user to enter search criteria when conducting a search. You need to create a qualifier for each field you want to include in the search view's search criteria. The more qualifiers you add when creating a search view, the more types of information users are able to search by to find the records they need.
You can define search qualifiers and the appearance of the Custom Search page on the Filter Display tab of the search view.
You can add the following items to the search view on the Filter Display tab:
•Visible qualifiers (see Visible and Invisible Qualifiers)
•Invisible qualifiers (see Visible and Invisible Qualifiers)
•Section Titles (see Creating Section Titles)
Note: If no qualifiers are specified in the search view, then no records are filtered out of the search results. Instead, all records for the object are listed.
