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