• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang yan ((auf tests) OR (aux tests)) ((housing bank) OR (housing a)) long sara ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yan ((auf tests) OR (aux tests)) ((housing bank) or (housing a)) long sara ;*".
