How to execute plain Redis queries in Java

I need to make native queries to Redis in the Java code. Is there a Java library or another way to do this?

I need something like this:

someRedisClient.execute("FT.SEARCH SOME_INDEX (@foo:bar*)")

I didn't find such feature in lettuce, lettusearch, redisson.

Jedis has sendCommand methods which supports what you want but with a caveat. The method signatures are as follows:

Object sendCommand(ProtocolCommand cmd, byte[]... args)
Object sendCommand(ProtocolCommand cmd, String... args)

As you can see, you must have an implementation of ProtocolCommand representing the actual command. It is commonly done by enum.

public enum Command implements ProtocolCommand {
  
  FT_SEARCH("FT.SEARCH");
  
  private final byte[] raw;
  
  private Command(String str) {
    raw = str.getBytes();
  }
  
  @Override
  public byte[] getRaw() {
    return raw;
  }
}

After that,

jedis.sendCommand(Command.FT_SEARCH, "SOME_INDEX", "(@foo:bar*)");

Yes, the command arguments are separate strings, instead of concatenated by space.
