• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang guang) OR (((yang yang) OR (wang yang)))) hui liu yang jun ying shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang guang) or (((yang yang) OR (wang yang)))) hui liu yang jun ying shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang guang) or (((yang yang) OR (wang yang)))) hui liu yang jun ying shu ;*.
