CMS.QUERY
Syntax
CMS.QUERY key item [item ...]
Time complexity: O(n) where n is the number of items
ACL categories: @cms
Returns the estimated count of one or more items from the Count-Min Sketch stored at key.
The returned counts are estimates and may be higher than the true count (over-counting) due to hash collisions, but will never be lower than the true count.
Return
Array reply: An array of integers, one per item, representing the estimated count of each queried item.
