> Hi all! I'm working on building a searcher for a site. This site generates a lot of writes (new or modified documents) so we need to use some mechanism to ensure pagination consistency by using certain criteria (freshness or price in our cases). We began to use the search\_after parameter for solving our issues. This works fine until we realized that our query slow log started to have a lot of entries.

As the @mayya 's answer (Thx mayya!), I expected search\_after performance has improved at 7.16, so I looked over [7.16 release note](https://www.elastic.co/guide/en/enterprise-search/current/release-notes-7.16.0.html), but I can't find this update news.

You are looking at the wrong release notes, these are for our Enterprise Search product.

Elasticsearch 7.16 release notes are [here](https://www.elastic.co/guide/en/elasticsearch/reference/7.16/release-notes-7.16.0.html), and the item related to the sort optimization with after is this one:

"Add sort optimization with after from Lucene #64292"
