• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (chieu sach)) - hoang minh cua ban huong dan ((thanh lap) OR (thanh hai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sach)) - hoang minh cua ban huong dan ((thanh lap) OR (thanh hai))~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sach)) - hoang minh cua ban huong dan ((thanh lap) OR (thanh hai))*.
