The documentation and recommendation for using stored\_fields feature in ElasticSearch has been changing. In the latest version, stored\_fields is not recommended - [https://www.elastic.co/guide/en/elasticsearch/reference/7.9/search-fields.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.9/search-fields.html)  
Is there a reason for this?

Where as in version 7.4.0, there is no such negative recommendation - [https://www.elastic.co/guide/en/elasticsearch/reference/7.4/mapping-store.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/mapping-store.html)

What is the guidance in using this feature? Is using \_source filtering a better option? I ask because in some other doc, \_source filtering is supposed to kill performance - [https://www.elastic.co/blog/found-optimizing-elasticsearch-searches](https://www.elastic.co/blog/found-optimizing-elasticsearch-searches)

What is the best way to filter fields and not kill performance?

The documentation has only been updated for the most recent release (and also moved around), using source is recommended there as well. So is upgrading from 7.4 to 7.9 🙂
