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