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