To allow users to search according to the field contents, you can specify the following fields as search qualifiers on the Filter Display tab of a search view:
•Description field in history records
•Notes field in system records
•Custom fields of type Memo Text
Content search fields will be displayed in the search criteria section of the search screen so that users can type the text that they are seeking. A question mark (?) hyperlink displayed next to such fields allows users to select search operators.
You can also add the content search fields on the Results Display tab so that users can see the entire contents of the fields in the results. For details about field types and their storage sizes, see Field Types.
