• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((ka a) OR (k a)) test ((yang jin) OR (yuan ting)) ((hong g) OR (hong ghi)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((ka a) OR (k a)) test ((yang jin) or (yuan ting)) ((hong g) or (hong ghi)) ;".
• Adding a wildcard symbol may retrieve word variants: lang yan ((ka a) OR (k a)) test ((yang jin) or (yuan ting)) ((hong g) or (hong ghi)) ;*.
