Query members in a lexicographical range
Usage: zrangebylex key min max.
min and max are member bounds. Use -, + to query all members.
When specifying values for min/max, prefix them with [ or (.
Use [ to include the value and ( to exclude it.
This command requires all scores to be equal to get the intended result.
This command has no withscores option.
Example
| Command> | zrangebylex city - + |
| Result> |
0) Beijing 1) New Delhi 2) New York 3) Seoul |
| Command> | zrangebylex city "[New Delhi" + |

Using limit offset count
Usage: zrangebylex key min max limit offset count.
offset is the starting point, and count is the number of members to return.
offset can start from 0, and count must be 1 or greater. If count is 0, nothing is returned.
If limit is used, both offset and count are required.
Useful for paging.<

| Command> | zrangebylex city - + limit 0 2 |
| Result> |
0) Beijing 1) New Delhi |
| Command> | zrangebylex city - + limit 2 2 |
