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