• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) or (thien quan)) - ((hanh tang) OR (hanh mang)) vat dung duong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (thien quan)) - ((hanh tang) OR (hanh mang)) vat dung duong manh toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (thien quan)) - ((hanh tang) OR (hanh mang)) vat dung duong manh toan cao*".
