 Usage:

ZINTER numkeys key [ key ... ] [ WEIGHTS weight ] [ [ WEIGHTS weight ] ... ] [ AGGREGATE sum  min  max ] [ 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
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
.
