• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu tinh)) - hanh trung ((tam cong) OR (dam cong)) cong ban chan cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu tinh)) - hanh trung ((tam cong) OR (dam cong)) cong ban chan cap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chieu tinh)) - hanh trung ((tam cong) OR (dam cong)) cong ban chan cap*.
