Query for documents containing (or not containing) field

When ingesting documents with different schemas, it's difficult to be able to split the collection based on the fields which one schema contains (or is missing). Currently, there is no way to query for fields with an empty string, nor is it possible to query for fields which match a full wildcard value. If either of these query techniques were implemented it would be make searching for documents, especially in JSON collections, much easier. 

 

Also, for debugging purposes: when some enrichments don't get applied correctly for whatever downstream reason, it would be helpful to be able to query which documents are missing certain enriched fields so that reingestion can happen successfully.
