A Search Field Client Filter examines each record in a dataset. It looks for characters that match what has been provided as input. By default, it looks at the values of all attributes in each record. If it does not find a match, then it will hide that record on the client. The Search Field input does provide an option to constrain the search to a specific attribute.
