I have a set of documents that I'm getting from SQL Server that have a lot of fields that were never used and hence Null. I cannot change the schema however when I query these docs in ElasticSearch the number of empty fields is so much it slows me down a lot.
Is there a way to request a query that doesn't return Null valued fields? I don't want to specify each field that I do want as they still could be null. I just don't want the results to contain null values.
