dam rein » dam region, am rhein, der rein
wong yue » wang yue, hong yu

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yang ((di rein) OR (dam rein)) tang li ((wong shiu) OR (wong yue)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang ((di rein) OR (dam rein)) tang li ((wong shiu) or (wong yue)) ;*".
