• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) han china pei yang 2 ((long du) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yan)) han china pei yang 2 ((long du) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yan)) han china pei yang 2 ((long du) OR (long do)) ;*.
