Is there any way I can delete the data from redis using Poco::Redis if I know only the prefix name of the Key?

     sudo ./redis-cli -p 1000
      IP = 127.0.01 and port 1000
       KeyName USR:12345
               USR:13455
               USR:1234

I want to delete all the jeys but I know the Prefix name "USR". I didn't found any way ?Can we achive this in POCO::REDIS
