The Start with operator is used to select all those contacts that start with the value entered in the condition input field. This means that the operator implicitly uses wildcards to match the input field with the relevant attribute values in the database.
The Start with operator is not case sensitive.
Setting the First Name condition to Start with, with Sam as the input field value, selects all those contacts whose first name starts with Sam. Contacts whose first name is, for example, Sam, Samantha or Sammy are selected.
The Start with operator applies to string data types.
See Input field types for more about each input field.
