How can i insert a json and directly have new values mapped in correct format ? e.g. the field "amount" is not yet in my index and hence also not yet mapped. My index is having a lot of different values with a mapping already and i dont want to completely map all values new. How can i insert the document with telling how to map ? I want this json inserted with location as text and amount as numeric: > POST index/\_doc > { > "location": "Germany", > "amount": "15", > } ---

You just ingest data and Elasticseach will do the dynamic mapping: [https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-mapping.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-mapping.html) ---
