• If you are trying to use Boolean operators, they must be ALL CAPS: ho chau tinh - ((hanh trang) OR (thanh trung)) cua nhung cong trinh ((can cau) OR (ban cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - ((hanh trang) OR (thanh trung)) cua nhung cong trinh ((can cau) or (ban cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - ((hanh trang) OR (thanh trung)) cua nhung cong trinh ((can cau) or (ban cau))*.
