Hi Fulvio,
You mentioned: when I login with another user I get an error:" you are not authorized to view this link".
Are you getting this error from clicking the link "Asset created from model" ?
If so, then that is not related to the search it is related to a model configuration.
Locate the user role for this user. Then check the configurations assigned to this role and look for any local model configurations. The problem is either in the global model configuration or in a local model configuration.
There is likely a configuration setting for this user that prohibits access to this link.
If you cannot find the problem, then please put in a case with support to assist further.
HTH,
