public class CustomFacetSetExample
extends Object

Shows usage of indexing and searching FacetSetsField with a custom FacetSet implementation. Unlike the out of the box FacetSet implementations, this example shows how to mix and match dimensions of different types, as well as implementing a custom FacetSetMatcher.
