Method: Redis::Commands::SortedSets#zrevrangebylex

Defined in:
lib/redis/commands/sorted_sets.rb

#zrevrangebylex(key, max, min, limit: nil) ⇒ Object

Return a range of members with the same score in a sorted set, by reversed lexicographical ordering. Apart from the reversed ordering, #zrevrangebylex is similar to #zrangebylex.

Examples:

Retrieve members matching a

redis.zrevrangebylex("zset", "[a", "[a\xff")
  # => ["abbygail", "abby", "abagael", "aaren"]

Retrieve the last 2 members matching a

redis.zrevrangebylex("zset", "[a", "[a\xff", :limit => [0, 2])
  # => ["abbygail", "abby"]
