Description
Similar to #1797, when using SortedSetRangeByValue in ascending order and minimum value and a limit, I always get the same results.
zadd SORTEDSET 0 aaa
zadd SORTEDSET 0 bbb
zadd SORTEDSET 0 ccc
zadd SORTEDSET 0 ddd
zadd SORTEDSET 0 eee
zrangebylex SORTEDSET "(ccc" + LIMIT 0 10
1) "ddd"
2) "eee"
In C#:
database.SortedSetRangeByValue(cacheKey, minValue, take: count)
// cacheKey = "SORTEDSET", minValue = "(ccc", count = 100

Research direction
Start at the SortedSetRangeByValue entry point and reproduce the supplied C# call alongside the equivalent Redis ZRANGEBYLEX command, focusing on minimum values and LIMIT handling. Done means the client behavior is consistent with the Redis example and no longer returns the same results when the range should differ.
