• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (wai yan)) liang ((iii formen) OR (iii form)) von david hong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) OR (wai yan)) liang ((iii formen) or (iii form)) von david hong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) OR (wai yan)) liang ((iii formen) or (iii form)) von david hong ghi ;*.
