you can scan keys using scan command of redis. see documentation http://redis.io/commands/scan

example

scan 0 match "690-brand-*"

for node.js example see https://stackoverflow.com/a/37405810/6265117

you can use keys command if working on development environment or debugging , database not large. link - http://redis.io/commands/keys

note: keys not recommended production environments.
