Hi, I am indexing the data in which one of the document fields is JSON. I mapped this as an object in the data-mapping and I am able to index and search this JSON from Kibana. But in some of the records or documents, the data type of the fields inside the JSON are different. Ex: 1 Rec or Doc - JSON property is scratchpad : and scratchpad.input.f1 =\> is a string 2 Rec or Doc - scratchpad.input.f1 =\> is a object When this data is given as input to index, 1 Rec is indexed, But 2nd Rec index failed because elastic is expecting "scratchpad.input.f1" as a string, but found an object. Is there anyway to ignore these mismatch of the data type of the internal fields across docs ? Still maintaining JSON search capability after index. Any help is much appreciated. Regards, Tirumala Reddy ---

Hey, see the [`ignore_malformed`](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/ignore-malformed.html) option in the elasticsearch docs. --Alex ---
