Values are used to compare against fields. Depending on the field, there may be a list of predefined values available.
For example: The Facility.Building_Name field has a predefined value list that displays all of the buildings defined in an institution’s system. Other fields, such as the Patron.Assigned field, have predefined values of Yes, No, or [None]. Selecting a field value equal to [None] allows a user to find fields that contain no values.
If using the is one of or is not one of operators, the Lookup link can be used to select from a list of available values for the field. To select values, click on the Lookup link, then click in the checkbox(es) next to the value(s). If typing the values, separate the entries using a semicolon (;).
