Configuring Fixed Constraints automatically limits the results a user receives in the filter. Add attributes and attribute values that must match in order for objects to be displayed. When a constraint is added to a filter, objects will only be found if they meet the criteria of the constraint. One or many fixed constraints can be configured for a filter.
To create a fixed constraint:
In addition, complex fixed constraints can be configured. This can be accomplished by using a combination of parentheses and AND/OR operators to construct complex queries.
Parentheses can be used to group constraint items together. To specify a parenthesis before a constraint item, click the attribute row under the ( column. To specify a parenthesis after a constraint item, click the attribute row under the ) column. The parenthesis button toggle the parenthesis off and on.
The Connector column provides a drop-down list that allows you to specify how values are searched using the fixed constraint items. AND is selected by default. If AND is selected, multiple fixed constraints must be met in order for objects to be returned in the filter's results. If OR is selected, one of the fixed constraints items must be met in order for objects to be returned in the filter's results. You can use a combination of the AND and OR operators, coupled with the use of parentheses in order to yield the desired results.
You can move a configured fixed constraint attribute up and down in the list by selecting the attribute and clicking the up and down buttons on the right side of the screen to place the attribute in the correct position in the list. You can delete configured attributes by clicking the delete button with the red x next to the attribute.
