If an arg and rel is filled, there is no query entity

[schmmd]

If you search for (Edison, invent, *) you will get no entity card and we cannot disambiguate the entity.

We want to show an entity card when either argument is filled with an entity constrain and there is also a relation query term. I.e. for (arg1, rel, *) or (*, rel, arg2) when arg1 or arg2 is an entity constraint. We also want to do entity disambiguation in this case when arg1 or arg2 is not an entity constraint.
