• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (nana yaa)) wang yan chen ying jin ((song min) OR (song ming)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (nana yaa)) wang yan chen ying jin ((song min) OR (song ming)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (nana yaa)) wang yan chen ying jin ((song min) OR (song ming)) ;*.
