• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sang) OR (chieu sach)) - ((manh truong) OR (hanh trong)) dao nhung cong van tan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) OR (chieu sach)) - ((manh truong) OR (hanh trong)) dao nhung cong van tan cau*.
