• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc dien) OR (hoc dieu)) quang - nhan ((sinh cua) OR (dinh cuu)) nhung cong dan gian man.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc dien) or (hoc dieu)) quang - nhan ((sinh cua) OR (dinh cuu)) nhung cong dan gian man".
• Adding a wildcard symbol may retrieve word variants: ((hoc dien) or (hoc dieu)) quang - nhan ((sinh cua) OR (dinh cuu)) nhung cong dan gian man*.
