I see limitation on number of nested fields starting ES 2.3 - [https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-2.3.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-2.3.html)
I have defined a mapping with dynamic template in nested field and got the below exception
\> Caused by: MapperParsingException[Mapping definition for [\_def] has unsupported parameters: [dynamic\_templates : [{others={mapping={index=analyzed, omit\_norms=true, store=true}, match=\*}}]]]

Does this mean dynamic template cannot be defined in nested fields?

What does the mapping look like?

Please find the mapping below
\> {

\> "def": {
\> "\_all": {
\> "enabled": false

\> "\_source": {

\> }
\> },
\> "dynamic\_templates": [
\> {
\> "model": {
\> "mapping": {
\> "index": "not\_analyzed",

I have the same question. How can we define a dynamic template for fields which are of nested type?
