The search page for events is not working as expected

If you go to "Status -> Events" and then click on "Advanced Search", you'll see a big form to build a custom filter, and apply it to the events page.

I tried adding partial content on the node label, and click search, but the output is not filtered.

I tried adding partial content on the IP address, and click search, but the output is not filtered.

I tried selecting a service, and click search, but the output is not filtered.

If I apply several filter rules, I can see all of them on the URLs, but the output is not filtered.

It seems like the format for the filters is invalid.
