Create role with the following privileges:
Assign that role to a user, and log into Nexus Repo. Browse into a repository.
In the upper right corner of the browse view there will be an "advanced search..." link. Clicking it gives an authorization prompt. This is not a good user experience, the user is already logged in.
Expected: The link should be disabled if the user does not have search privileges.
Workaround: Grant the user the nx-search-read privilege
