• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang xueman) OR (wang xiuyan)) yang 3 ((chin chang) OR (china zhang)) nan wong shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xueman) or (wang xiuyan)) yang 3 ((chin chang) OR (china zhang)) nan wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xueman) or (wang xiuyan)) yang 3 ((chin chang) OR (china zhang)) nan wong shiu ;*.
