• If you are trying to use Boolean operators, they must be ALL CAPS: (((( international centre for mechanical science, courses AND lectures ) OR ( international centre for mechanical science, courses AND lecture ))) OR ( international centre for clinical science, courses AND lectures )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( international centre for mechanical science, courses and lectures ) OR ( international centre for mechanical science, courses and lecture ))) or ( international centre for clinical science, courses and lectures ))".
• Adding a wildcard symbol may retrieve word variants: (((( international centre for mechanical science, courses and lectures ) OR ( international centre for mechanical science, courses and lecture ))) or ( international centre for clinical science, courses and lectures ))*.
