• If you are trying to use Boolean operators, they must be ALL CAPS: ((zhang yan) OR (dong skin)) ((ka a) OR (k a)) west bank long ((chong nam) OR (chong wan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yan) or (dong skin)) ((ka a) or (k a)) west bank long ((chong nam) OR (chong wan)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yan) or (dong skin)) ((ka a) or (k a)) west bank long ((chong nam) OR (chong wan)) ;*.
