Thanks for you reply, Daniel.

I have to confess that I didn't the manual thoroughly. However, I do not want multiple values.
The "Arts, Music, Literature" is just one subject instead of three. So my question is still not answered, right? Is there any way to accomplish this?

Let me guess, you didn't read the manual and are trying to use commas to
list multiple values without looking on the proper way to do an or query?
Commas are taken as literal values, || is used inside of a block to
separate multiple values.

        {{#ask: [[subject::Arts||Music||Literature]]
        | ?title
        | ?author
        }}

Or if you were trying to do an AND:

        {{#ask: [[subject::Arts]] [[subject::Music]] [[subject::Literature]]
        | ?title
        | ?author
        }}
