• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sach - hanh chinh tham dung cong van ((tan ca) OR (tay cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) sach - hanh chinh tham dung cong van ((tan ca) or (tay cao))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) sach - hanh chinh tham dung cong van ((tan ca) or (tay cao))*.
