• 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 clinical science, courses AND lectures ) OR ( international centre for clinical science, courses AND lecture )))).
• 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 clinical science, courses and lectures ) OR ( international centre for clinical science, courses and lecture ))))".
• Adding a wildcard symbol may retrieve word variants: (( international centre for mechanical science, courses and lectures ) or ((( international centre for clinical science, courses and lectures ) OR ( international centre for clinical science, courses and lecture ))))*.
