I recommend this old but gold advent post from 3 years ago: [Dec 12th, 2018: [EN][Elasticsearch] Automatically adding a timestamp to documents](https://discuss.elastic.co/t/dec-12th-2018-en-elasticsearch-automatically-adding-a-timestamp-to-documents/159314)

It shows how to use a pipeline that adds an ingest timestamp to every document you push. That's the most accurate way you can use and it allows you to lower the value for `delay`. Note that by default lucene uses a refresh interval of `1s`, so you should not set `delay` to a lower value, but e.g. use `2s`. Of course you can tweak this further, but I guess that should already meet recency requirements for most users.
