• If you are trying to use Boolean operators, they must be ALL CAPS: fan ((yi chang) OR (boon chong)) yu chen ((((wang li) OR (wang lin))) OR (yang judy)) shang kai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fan ((yi chang) or (boon chong)) yu chen ((((wang li) OR (wang lin))) or (yang judy)) shang kai ;".
