• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (yuan chang)) yang iii gene we thank kong (sar OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yuan chang)) yang iii gene we thank kong (sar OR saur) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yuan chang)) yang iii gene we thank kong (sar OR saur) ;*.
