Method: Redis::SortedSet#intersection

Defined in:
lib/redis/sorted_set.rb

#intersection(*sets) ⇒ Object Also known as: intersect, inter, &

Return the intersection with another set. Can pass it either another set object or set name. Also available as & which is a bit cleaner:

members_in_both = set1 & set2

If you want to specify multiple sets, you must use intersection:

members_in_all = set1.intersection(set2, set3, set4)
members_in_all = set1.inter(set2, set3, set4)  # alias

Redis: SINTER
