ZINTER

Returns the intersect of multiple sorted sets.

Usage: ZINTER numkeys key ... [WEIGHTS weight ...] [AGGREGATE aggregate] [WITHSCORES withscores]
Complexity: O(N*K)+O(M*log(M)) worst case with N being the smallest input sorted set, K being the number of input sorted sets and M being the number of elements in the resulting sorted set.
Since: 6.2.0
ACL Categories: @read, @slow, @sortedset
Command flags: READONLY

This command is similar to ZINTERSTORE, but instead of storing the resulting sorted set, it is returned to the client.

For a description of the WEIGHTS and AGGREGATE options, see ZUNIONSTORE.
