• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) OR (wang liang)) ya a burden sharing ((((jin cong) or (li cong))) or (jin ying)) shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang liang)) ya a burden sharing ((((jin cong) OR (li cong))) OR (jin ying)) shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang liang)) ya a burden sharing ((((jin cong) or (li cong))) or (jin ying)) shu ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang liang)) ya a burden sharing ((((jin cong) or (li cong))) or (jin ying)) shu ;*.
