Exceptions thrown
[[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a sorted set

Out of range indexes will not produce an error. If start is larger than the largest index in the sorted set, or start > end, an empty list is returned. If end is larger than the end of the sorted set Redis will treat it like it is the last element of the sorted set. The indexes are inclusive.

Exceptions thrown
[[scredis.exceptions.RedisErrorResponseException]] if key contains a value that is not a sorted set
Note
Both start and stop are zero-based indexes, where 0 is the first element, 1 is the next element and so on. They can also be negative numbers indicating offsets from the end of the sorted set, with -1 being the last element of the sorted set, -2 the penultimate element and so on. Out of range indexes will not produce an error. If start is larger than the largest index in the sorted set, or start > end, an empty list is returned. If end is larger than the end of the sorted set Redis will treat it like it is the last element of the sorted set. The indexes are inclusive.
