> The current version of "intersect_count" only support "intersect" operation.
> While in some cases, we may union some collections(bitmaps) first, and then
> intersect with other collections. For example:
>
> intersect_count(user_id, page_id, array['search', 'view', 'order']);
> -- this calculation how many users did "search", and then "view", and then
> make the "order".
>
> intersect_count(user_id, page_id, array['search|view', 'order']);
> -- this calculation how many users did "search" or "view" (any of them) , and
> then make the "order".
