Description

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
