So the use case would be that you have a content with optional field and distinguish between having it filled in with certain value or not filled at all.\r\n\r\nExample: \r\n\r\nID | field1 | field2\r\n---|------|------\r\n1 | value1 | |\r\n2 | value1 | value2 |\r\n\r\nQ1: `?query={\"field1\": \"value1\", \"field2\": null}` will return id `1`\r\nQ2: `?query={\"field1\": \"value1\", \"field2\":\"value2\"}` will return id `2`\r\n\r\nI noticed that in the implementation you're currently using a `JSONObject.put` which in case I call `query.put(\"field1\", null)` actually removed the key `field1` from the object instead of adding it as a value.\r\n\r\nIs there currently a workaround how to query values like that (except querying all models that fit it and check for the field manually)?
