• If you are trying to use Boolean operators, they must be ALL CAPS: (( te ((sac tinh) OR (dac tinh)) lai gia tuong ) OR ((( tu ((cach minh) OR (cach mang)) bi gia tuong ) OR ((( tu sach hinh bai giai tuong ) OR ( su ((cach kinh) OR (cac tinh)) bai giai tuong ))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te ((sac tinh) or (dac tinh)) lai gia tuong ) or ((( tu ((cach minh) or (cach mang)) bi gia tuong ) or ((( tu sach hinh bai giai tuong ) or ( su ((cach kinh) OR (cac tinh)) bai giai tuong ))))))~".
