• If you are trying to use Boolean operators, they must be ALL CAPS: fan ((yi chang) OR (joon chang)) ((yu chen) OR (yu cheng)) ((wang li) OR (yang judy)) shang kai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fan ((yi chang) or (joon chang)) ((yu chen) OR (yu cheng)) ((wang li) or (yang judy)) shang kai ;".
• Adding a wildcard symbol may retrieve word variants: fan ((yi chang) or (joon chang)) ((yu chen) OR (yu cheng)) ((wang li) or (yang judy)) shang kai ;*.
