While exporting the metadata of SystemAdminstrator Profile I am getting a user permission " AllowUniversalSearch" but not able to figure out from where can we set this permission as it is not visible on System Admin profile. I searched over net about this permission but could find nothing related to this
You would create a
permission set to enable it. See the Security Workbook - Create Permission Sets and Permission Set Best Practice: You Should Try THIS Out at Home.
