• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yan) OR (yan liang)) ((yuan fei) OR (((than china) OR (wuhan china)))) hui yang ka long d ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) or (yan liang)) ((yuan fei) or (((than china) OR (wuhan china)))) hui yang ka long d ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) or (yan liang)) ((yuan fei) or (((than china) OR (wuhan china)))) hui yang ka long d ;*.
