Hi,
I have an index that is being populated in realtime. However, I have one field in the index which I don't need anymore. Is there anyway to delete just one field from an index for all documents?
Thanks in advance.
Cheers,
Balaji

Hi @astrobalaji,
you can use update by query to remove the field from all docs, see: [https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html) . You have to use a script in order to remove the field from each document.

Thanks 🙂
But the field is still in the mapping though. Is it possible to delete the field from the mapping??

You can't. You need to create a new index for that.
Or if you have a platinum license, you can hide this field from all the users but the "admin".
