I would like to make a pie with one slice being "good" and the other being "bad". a document is considered "bad" if it has a certain field. How can I do this? ---

there are a couple of ways you could try to solve this: - at index time create additional field like `good` with boolean value - or create a scripted field to check for this condition - or use filter aggregation, where one filter would be: `{"exists":{"field":"machine.os.raw"}}` and the other one: `{"bool":{"must_not":{"exists":{"field":"machine.os.raw"}}}}` i hope this gives you some ideas and helps you to solve your problem. ---
