• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu tinh - ((((anh tang) OR (anh bang))) or (nhanh lang)) quan dung cong san toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((((anh tang) OR (anh bang))) OR (nhanh lang)) quan dung cong san toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((((anh tang) OR (anh bang))) or (nhanh lang)) quan dung cong san toan cao*".
