How to search fields with dates in KQL

So this link:

nor this link:

document how to use KQL to search fields with dates. We have a creation_date field (not the @timestamp) and would like to search on it. When I tried to search:

creation_date > 2019-11-04T09:00:00

it told me that I was using lucene syntax. I also tried:

creation_date > -2d

But got an error.

Is there a page/post that has already covered this?


It SEEMS to be this link:

But I still get complaints that I'm using lucene...

There is a selector at the end of the search bar that lets you switch from Lucene to KQL. I think starting 7.4.0 KQL has been made the default one.
