Understanding Automatic Search Conditions
Search/Match uses phone and email values to perform the search only when a phone or email value is marked as preferred. Therefore, to use PhoneRule and EmailAddressRule inside a search rule triggered automatically when you save a new ID, the ID must have a preferred phone number and preferred email address.
When Address1Rule, Address2Rule, Address3Rule, Address4Rule, CityRule, CountryRule, CountyRule, PostalRule or StateRule are inside a search rule triggered when you save a new person ID, Search/Match uses the address fields for only the home address type to perform the search. That is, if any address type other than HOME is entered, Search/Match does not use the address fields as search criteria.
