A search interface allows you to control record search behavior for groups of one or more attributes.
You can use a search interface to control the behavior of search against a single standard or managed attribute, or to simultaneously search across multiple attributes.
For example, if a data set contains both an Actor standard attribute and Director managed attribute, a search interface can provide the user the ability to search for a person’s name in both. A search interface’s name is used just like a normal attribute when performing record searches. By default, a record search query on a search interface returns results that match any of the attributes in the interface.
