How to get all the following data according to the prefix of the key

I have a data structure like this in redis and I want to get all the data under HAYY:DeviceEXT based on the prefix of the key, which are all the same entities

Has been answered a few times, there will be no search in this library. A simple cache does not need to search for keys.
Use Redis directly if you need it, those operations are very expensive.
