Hi Experts,
I read "[https://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html)" and got to know that we can set doc\_value to true. Even a code has been mentioned in this link. Since I am new to ELK so my question is where I need to place this code or where I need to mention "doc\_values": true. Do I need to mention it in a file or something if yes then what is the name of that file .
Please suggest

Hi,
You can find some explanations and examples about doc values at [https://www.elastic.co/guide/en/elasticsearch/guide/master/doc-values.html](https://www.elastic.co/guide/en/elasticsearch/guide/master/doc-values.html)

You set field data in the mapping of a field.
Using the code in the docs you can run that in Sense, or use curl, to send it to Elasticsearch.
