Type	Description
EntityQueryBuilder	Returns the amended EntityQuery.

Remarks

The resulting EntityQuery will match all entities matched by any individual query description. In terms of set theory, the query matches the union of its query descriptions, not the intersection.

            EntityQuery query = new EntityQueryBuilder(Allocator.Temp)
                .WithAll<Parent>().WithNone<Child>()
                .AddAdditionalQuery()
                .WithAll<Child>().WithNone<Parent>()
                .Build(this);

The EntityQuery created from this builder matches entities that have a Parent component but no Child component OR have a Child component but no Parent component.
