Empty equalTo to get all results

[cre8]

Is it possible to get all results with the same query, so I can use it for 'large', 'small' and all values?

const subject = new Subject(); // import {Subject} from 'rxjs/Subject';
const queryObservable = af.database.list('/items', {
  query: {
    orderByChild: 'size',
    equalTo: subject 
  }
});

subject.next('large'); //only large
subject.next('small'); // only small
subject.next(''); // should return both, but returns nothing

a simple subject.next(null) would be enough ;)
