What is the order of returned elements from the Redis command ZRANGEBYLEX? Or is it not defined? I understand elements are stored according to lexicographical ordering which allows Redis to support various types of queries. However documentation does not state how the retuned element list is ordered. From all the tests I have done so far it looks like they are ordered lexicographically but I like to get this confirmed.

Hi Manusha,

The order in which the replies are returned is indeed lexicographical in this case. Similarly, when not using lexicographical ordering, replies are returned ordered by their scores (and lexicographically for identical scores).
