Guys,  
In a system where u could expect a decent rate of update request, say 10% of overall documents getting updated daily, what is the merge setting for -

> [Merge | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-merge.html#tiered)  
> index.merge.policy.reclaim\_deletes\_weight

one would recommend so we have the deleted document count very much under control. We have seen in cases, the deleted document count goes up to 30% and stays there. We end up doing periodic expunge delete.
