This Condition located on the Miscellaneous category tab in Search Builder looks at information that was captured on a visitor/connection card and is edited on the Profile > Entry tab of the people record. The options will vary from church to church.
The Interest Point is basically the answer to ‘How did you hear about us?’ Each church can edit these options in the Lookup Codes.
A use case for this Condition would be finding out how many people found out about your church because of a friend. Select Equal Friend.
Remember, each database will have an initial set of options for the Interest Point. However, your System Admin can change these to fit whatever options you offer on your guest cards for how someone became interested in your church.
