• If you are trying to use Boolean operators, they must be ALL CAPS: yang liu yang ((yulu chen) OR (hong cheng)) chan eng ((chun h) OR (chun i)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang liu yang ((yulu chen) or (hong cheng)) chan eng ((chun h) OR (chun i)) ;*".
