• If you are trying to use Boolean operators, they must be ALL CAPS: ((ying chang) OR (yu yang)) wang wei strange ((things using) OR (savings using)) drag bei ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ying chang) or (yu yang)) wang wei strange ((things using) OR (savings using)) drag bei ;*".
