Hi It seems if the field has multi-values (separate by ",") then when doing aggregation it will cause discrepancy. Is there a way to have correct numbers? ---

Can you provide some more detail on your issue? Please include as much detail as possible including: - A Sample document - The mapping for you index - The query you are trying to run - An explanation of why you think there is a discrepancy between what you expect and the response you see - The response JSON from your query Since this will be quite a lot of JSON to paste here, please instead paste the JSON requests and responses in a [Gist](http://gist.github.com) and link to it here. Thanks ---
