• Performing a fuzzy search may retrieve terms with similar spellings: done ((hoang h) or (hoang sy)) ((hua gene) OR (a gene)) ((yuan ming) or (sang minh)) cong seo ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: done ((hoang h) OR (hoang sy)) ((hua gene) OR (a gene)) ((yuan ming) OR (sang minh)) cong seo ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done ((hoang h) or (hoang sy)) ((hua gene) OR (a gene)) ((yuan ming) or (sang minh)) cong seo ;".
• Adding a wildcard symbol may retrieve word variants: done ((hoang h) or (hoang sy)) ((hua gene) OR (a gene)) ((yuan ming) or (sang minh)) cong seo ;*.
