• Performing a fuzzy search may retrieve terms with similar spellings: ((wang hong) OR (wang lihong)) ((yang hua) or (yang di)) gene yan ji ((won sau) or (wong sam)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang hong) OR (wang lihong)) ((yang hua) OR (yang di)) gene yan ji ((won sau) OR (wong sam)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang hong) OR (wang lihong)) ((yang hua) or (yang di)) gene yan ji ((won sau) or (wong sam)) ;*".
