Lucene (Or KQL) query to filter current day of week

Hi there!

I have some data on Elasticsearch with a datetime field.

I would like to filter all the data where the dayofweek is the same as today's... this way, I would be able to get all friday's data, saturday's data, etc dynamically. (eg without changing the day of week each day)

I try a lot of things but I'm stuck...

In discover, I tried the following query expression (in Lucene) :


Of course, it doesn't recognize the now.dayOfWeek

Is is only possible to achieve something like that?

Best regards,
