• If you are trying to use Boolean operators, they must be ALL CAPS: ((ke san) OR (ke dan)) ky nang x hoi. ((hieu ve) OR (hieu van)) nam thuc va dinh lam cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ke san) OR (ke dan)) ky nang x hoi. ((hieu ve) or (hieu van)) nam thuc va dinh lam cua te".
• Adding a wildcard symbol may retrieve word variants: ((ke san) OR (ke dan)) ky nang x hoi. ((hieu ve) or (hieu van)) nam thuc va dinh lam cua te*.
