• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y trung xa hoi. ((hieu ve) OR (lieu va)) cam xuc ((van hanh) OR (van anh)) thoi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y trung xa hoi. ((hieu ve) or (lieu va)) cam xuc ((van hanh) OR (van anh)) thoi cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach y trung xa hoi. ((hieu ve) or (lieu va)) cam xuc ((van hanh) OR (van anh)) thoi cua triet*.
