Redis ZREMRANGEBYRANK command removes all elements in the sorted set stored at the key with the rank between start and stop. Both start and stop are 0-based indexes with 0 being the element with the lowest score. These indexes can be negative numbers, where they indicate offsets starting at the element with the highest score. For example: 1 is the element with the highest score, -2 the element with the second highest score and so forth.
Integer reply, the number of elements removed.
Following is the basic syntax of Redis ZREMRANGEBYRANK command.
