As I think @RyouBakura was alluding to, the slash is supposed to mean that there are two different definitions present, so you should be able to just type one of the definitions, or type both but separate them with a semicolon (or possibly a space )
Thank you both.
I also thought about space at first, but it wont work because with IME space is mapped to “convert” command, it will convert hiragana into kanji (so it will be wrong answer). Semicolon might work.
