• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien thanh - hanh luat van duong ((cong dan) OR (huong dan)) ((than cau) OR (than cap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien thanh - hanh luat van duong ((cong dan) OR (huong dan)) ((than cau) or (than cap))".
• Adding a wildcard symbol may retrieve word variants: hoc thien thanh - hanh luat van duong ((cong dan) OR (huong dan)) ((than cau) or (than cap))*.
