• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (chieu sang)) - thanh thuong cua dang cong ((tac toan) OR (hach toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chieu sang)) - thanh thuong cua dang cong ((tac toan) or (hach toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) OR (chieu sang)) - thanh thuong cua dang cong ((tac toan) or (hach toan)) cau*.
