How to make a query like this?

noteBox.query() .equal(Note.title, queryString) .link(Note.tags).totalRecordsGreaterThan(0) .build() .find();

For now you can use query filters to achieve this.

Let's see if that would be a feature of a more general interest to be implemented in the core.

This is related to #677 asking for an isEmpty condition on ToMany.
