Search logic and groups

There are two primary search logics to choose between:

ALL: To be included people must mach ALL of the criteria you include in the search.

Search returns people who match criteria 1 AND criteria 2 AND criteria 3

ANY: To be included people must match ANY of the criteria you include in the search

Search returns people who match criteria 1 OR criteria 2 OR criteria 3

Most often you will want to choose the default ALL search logic for criteria you want to meet to be included and the default ANY search logic for exclusions. However for more complex searches where you may need different logic for different criteria. You can do this using groups.

Groups

Groups allow you to group criteria together and apply a different logic to the primary search logic. 

Normally for including people, you want them to meet all of the criteria and use the ALL logic. However there may be one criteria, like area or campaign activity where you want to include people that are in any of the areas or any of the campaigns. So for this criteria you put the different options into a group with the ANY logic.

For example if you are creating an audience of people who are active members AND was included in campaign A OR campaign B you can use a group for campaign A and campaign B search criteria and apply to ANY logic to this group.

When using groups make sure to sense check the number of people returned, if the number is different from your expectations, check over the logic using the summary on the page:
