Filter Groups dialog box

Used to define filter groups. A filter group lets you use existing filters to define new filter criteria.

Opens when you right-click on a filter name, then select Filter Group in the Level Manager dialog box.

Edit > Insert Filter(s)

Opens the Select Filters dialog box, which lets you insert one or more filters into the Filter Groups list box.

Select Filters dialog box

Filter Groups list box

Lists the expressions that define the filter group. A filter group uses existing filters and set-based operators to define filter criteria.

Set-based operators include: | (or), & (and) , or – (minus).

For example, suppose that Filter C uses a filter group that includes Filters A and B. If the levels that match Filter A criteria are Levels 1, 2, and 3, and levels that match Filter B criteria are Levels 3, 4, and 5, then the levels for Filter C depend on the filter group expression entered:

Filter Group Expression	Levels that Match Filter Group Criteria
“Filter A” | “Filter B”	Levels 1, 2, 3, 4, 5
“Filter A”& “Filter B”	Level 3
“Filter A”– “Filter B”	Levels 1,2

OK

Accepts the filter group expressions and closes the dialog box.

Cancel

Closes the dialog box without accepting the filter group expressions.

Clear

Clears the filter group expressions from the list box.
