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