• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (chao chu)) sach - hanh dung cua nhung cong ((dan toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (chao chu)) sach - hanh dung cua nhung cong ((dan toan) OR (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (chao chu)) sach - hanh dung cua nhung cong ((dan toan) OR (dan than)) cau*.
