• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) OR (chieu sach)) - thanh trung ((cua khong) or (cua thuong)) cong dan thanh hai~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - thanh trung ((cua khong) OR (cua thuong)) cong dan thanh hai.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu sach)) - thanh trung ((cua khong) or (cua thuong)) cong dan thanh hai".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu sach)) - thanh trung ((cua khong) or (cua thuong)) cong dan thanh hai*.
