I want to use SQL in expression to filter message properties when consuming messages, but it seems that I cannot get the messages I want. I put "Tag=test AND creator=xx" in expression and I want to filter messages with tag test and property {creator=xx}. How should I get this done?

It only supports "||" in expression at present.

thanks, do you plan to support others in the future?

There is no plan in the c++ client. Maybe you can look at the new client project.
