Hi,  
I have the feeling this step is wrong:

> **[Run downsampling manually | Elasticsearch Guide \[8.6\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.6/downsampling-manual.html)**

This query won't return an aggregation, only hits:

Or could it be that the previous step is a post and not a get?

Yep you are right, running the `_search` is a search and not an aggregation. Perhaps the `Re-run your search query to view the aggregated time series data.` should be after the `_downsample` is run, but not totally sure there.

Are you open to raising a bug report for the documentation on [Sign in to GitHub · GitHub](https://github.com/elastic/elasticsearch/issues/new/choose) so we can address it?

Thanks @warkolm I added it [Wrong step in documentation for downsampling · Issue #95017 · elastic/elasticsearch · GitHub](https://github.com/elastic/elasticsearch/issues/95017)

But now my question the aggregation query works fine, but when I do a \_downsampling, the new index is empty. and I don't know why
