A collection of FieldListFilters for object list filtering in the django administrator.
Multiple selection filters allow filtering on one or more filter values. The following multiple selection filters are available:
- UnionFieldListFilter: filters results matching ANY of the filter values. Similar to the Union operation on sets.
- IntersectionFieldListFilter: filters results maching ALL of the filter values. Similar to the Intersection operation on sets.
Import the filter and add it as a FieldListFilter implementation to the list_filter attribute of a ModelAdmin as described in the Django Documentation.

class CountryAdmin(admin.ModelAdmin):
list_filter = (
('continent', UnionFieldListFilter),
'languages'
)
