• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien hach - thanh ((trung cua) OR (truong cua)) ((nhung cong) OR (dung cong)) tan cao cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien hach - thanh ((trung cua) or (truong cua)) ((nhung cong) OR (dung cong)) tan cao cap~".
• Adding a wildcard symbol may retrieve word variants: hoc thien hach - thanh ((trung cua) or (truong cua)) ((nhung cong) OR (dung cong)) tan cao cap*.
