ZRANGEBYLEX - Upstash Documentation

Prefer ZRANGE with BYLEX in new code: ZRANGE <key> <min> <max> BYLEX [LIMIT <offset> <count>].

Use ZRANGEBYLEX to list the members of a sorted set that fall in a lexicographic range. Bounds are written [member for inclusive and (member for exclusive, with - and + standing for the lowest and highest possible members. LIMIT <offset> <count> pages through the result. The ordering used here is the byte order of member names, which is only meaningful when every member has the same score. Giving all members score 0 turns a sorted set into a sorted string index, which is how prefix lookups and autocomplete are built on top of it.

Syntax

ZRANGEBYLEX <key> <min> <max> [LIMIT <offset> <count>]

Arguments

Argument	Required	Repeatable	Description
`<key>`	Yes	No	Redis key targeted by the command.
`<min>`	Yes	No	Lexicographic minimum: `-`, `+`, `[member` (inclusive), or `(member` (exclusive).
`<max>`	Yes	No	Lexicographic maximum: `-`, `+`, `[member` (inclusive), or `(member` (exclusive).
`LIMIT <offset> <count>`	No	No	Skip `<offset>` matches and return at most `<count>`; a `<count>` of `-1` returns all remaining.

Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.

Protocol	Reply
RESP2	Array of bulk-string members
RESP3	Array of bulk-string members

Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

Examples

TCP examples use the TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
