• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang liang) OR (yan liang))) or (yang guang)) yuan hui pei yang 3.2 ((long d) or (long du)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang liang) OR (yan liang))) OR (yang guang)) yuan hui pei yang 3.2 ((long d) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang liang) OR (yan liang))) or (yang guang)) yuan hui pei yang 3.2 ((long d) or (long du)) ;*".
