Hi All , i have an artifact which is sending logs in elastic for about 5 months. (every month one index) . now all of a sudden business is saying one of the values in the old logs is wrong. say eg: the log field name is "average time " . now there is a work around , i can create scripted field and hide this old feild in my kibana visualization . now my scripted field will have the new value . but i am looking a way where i can change the old value and kind of do some re-index thing . so that no scripted feild is involved. all index sizes are of few MBs in my case. more than 400 doc in every index. any idea how to do it ? ---

Hello, You can use the [Reindex API](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html). As you can see, that includes the ability to provide a script for updating the documents. An alternative to providing the script would be to set up an [ingest pipeline](https://www.elastic.co/guide/en/elasticsearch/reference/current/pipeline.html) configured with the [rename processor](https://www.elastic.co/guide/en/elasticsearch/reference/current/rename-processor.html). ---

I hope this suggestion is to change the field value of any of the individual log entry inside all the document. (Which are pertaining to old index ) against the option of creating a log field new entry. Thank you for the suggestion. I will get back in couple of days to close this thread.meanwhile any more suggestions u wanna give pls welcome 😊 ---

Oh, I see, you want to fix the value in the original field. You can use the [script processor](https://www.elastic.co/guide/en/elasticsearch/reference/current/script-processor.html). ---

Not scripted field, script processor in the ingest pipeline when you reindex. ---
