 ==== Limits for JSON Objects
-
-You can't use `ignore_malformed` to index JSON objects into field datatypes used
-for other data formats, like `text` or `integer`.
-
-Similarly, `ignore_malformed` does not support datatypes used for JSON objects, including:
+You can't use `ignore_malformed` with the following datatypes:
 
 * <<nested, Nested datatype>>
 * <<object, Object datatype>>
-* <<range, Range datatypes>>
+* <<range, Range datatypes>>
+
+You also can't use `ignore_malformed` to ignore JSON objects submitted to fields
+of the wrong datatype. A JSON object is any data surrounded by curly brackets
+`"{}"` and includes data mapped to the nested, object, and range datatypes.
+
+If you submit a JSON object to an unsupported field, {es} will return an error
+and reject the entire document regardless of the `ignore_malformed` setting.
