+This command is similar to `ZUNIONSTORE`, 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`.
+
+@return
+
+@array-reply: the result of union (optionally with their scores, in case the
+`WITHSCORES` option is given).
+
+@examples
+
+```cli
+ZADD zset1 1 "one"
+ZADD zset1 2 "two"
+ZADD zset2 1 "one"
+ZADD zset2 2 "two"
+ZADD zset2 3 "three"
+ZUNION 2 zset1 zset2
+ZUNION 2 zset1 zset2 WITHSCORES
+```
