I was looking for a feature where i can pass first name, last name as plain string to Elasticsearch and just index these fields so i can search but do not store them in source (Due to PII data).

Came across this `copy_to` feature where i can store multiple fields from source but the original fields need to be there in source.

Any suggestions please.

Thanks

Welcome to our community! 😃

You need to disable that in the mapping, see [https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-source-field.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-source-field.html)

Thanks @warkolm,

This is exactly what i was looking for, I didn't know that we can exclude certain fields from `_source ` after indexing is done so they are only available for search and not in the `_source` as plain text.
