Hi everyone,

I'm currently trying to filter out a URL pattern on Kibana. We have already amended the mapping to make sure URLs are not split up due to being a analyzed\_field.

I want to filter out all URL of a specific field "x" that contain 8 numbers in a row.

e.x. [www.domain.com/xx/yy/d12345678](http://www.domain.com/xx/yy/d12345678)

I assume I need some sort of regex but can't sort out how it should look like

Can anyone help me out with it?

Hi Khalah,

Thanks for your reply!

I'd seen this but I'm afraid I need more assistance as I'm not really familiar with regex. Thanks anyway
