• If you are trying to use Boolean operators, they must be ALL CAPS: wang xiao yang ((hua ren) OR (yu chen)) yang jin ((zong yu) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiao yang ((hua ren) or (yu chen)) yang jin ((zong yu) OR (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiao yang ((hua ren) or (yu chen)) yang jin ((zong yu) OR (wong yue)) ;*.
