hoc truong » hoc thuong, hoc trong, moi truong
trung hoc » trung quoc
theo chu » theo chieu, cho chu, theo yeu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (chao chu)) xanh - thanh trung hoc truong phuong ((ban toan) OR (bai toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (chao chu)) xanh - thanh trung hoc truong phuong ((ban toan) or (bai toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (chao chu)) xanh - thanh trung hoc truong phuong ((ban toan) or (bai toan)) cao*.
