• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty hoang xa hoi. ((hieu ve) OR (hieu va)) ((cau phuc) OR (chau phu)) va danh vai va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty hoang xa hoi. ((hieu ve) or (hieu va)) ((cau phuc) OR (chau phu)) va danh vai va triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty hoang xa hoi. ((hieu ve) or (hieu va)) ((cau phuc) OR (chau phu)) va danh vai va triet*.
