> When documents doesn't contain value for field then, with collapse either those documents could be either ignored(default), collapsed(one document is chosen) or expanded(all are returned). This is controlled by {{nullPolicy}}
> When {{nullPolicy}} is {{collapse}}, it would be nice to return all documents with {{null}} value in expand block if {{expand=true}}
> Also, when used with {{expand.field}}, even then we should return such documents
