Hello, I clean my indexes in the elastic with the script below:

POST /aplicacao/\_delete\_by\_query  
{  
"query": {  
"range": {  
"timeLog": {  
"lte": "now-5M"  
}  
}  
}  
}

"aplicacao

 ![elastic-409](https://us1.discourse-cdn.com/elastic/original/3X/7/d/7d05ee5b90ab7a0534f0072adcebcc83a74cfcb9.jpeg)  
" is the name of the index, I leave only the last 5 months and delete the previous ones, but now version\_conflict\_engine\_exception errors with status 409 are appearing.

Is there any parameter that I can put in the script so that it can proceed with the delete?

I attached the printout of the error

See the `conflicts` parameter in the docs - [Delete by query API | Elasticsearch Guide [8.6] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.6/docs-delete-by-query.html)

Also you should really be using time based indices here (via [ILM](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-lifecycle-management.html)), rather than this approach.

Hello, thank you very much for the reply..

I took a look at the link that passed referring to Delete by query ...

Is there any parameter that I can insert in my delete query to delete it even if there is a conflict?

Remembering that I am deleting older data and leaving only the current 5 months, would there be any problem deleting even having conflicts?

Thanks !!
