I added a document as site admin to a public folder. If I search for it as an admin, I can find it. But if I try to search for it as a common user, it can't find it. Even if the users can see and open it inside the folder, not appears in the search results. I am using the default view of the folder, so that option is not the reason. The folder is public for anyone so I don't know how the search results are different. The common users have "contribute" permission and I am using SP 2016. Thank you for any advice!
UPDATE: Looks like the contributors can't even find the folders as search result. (They can see or open them manualy.)
