Global search shows Index Names. How to avoid that, as they spam result?

In the new Kibana 8.17.1 (coming from 8.11.4) the global search now find index names when I search. This makes it difficult to use. I can see i can wrtie tag:search but that makes it slow and much less useful than just using discover > open.

Is there a Kibana setting which prevents it from displaying index names in the search field?

I can see it doesn't show data-stream hidden indices, so I guess when we are fully migrated and all our old indices have been auto-deleted due to age, then the problem will vanish. But that's a long time to wait....
