• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (lang judy))ng ya yu chen ((chang amin) OR (chang ann)) ((hong 7) OR (hong ng)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (lang judy))ng ya yu chen ((chang amin) OR (chang ann)) ((hong 7) or (hong ng)) ;".
