• Performing a fuzzy search may retrieve terms with similar spellings: ((theo chieu) or (doi chieu)) sach - ((hanh manh) OR (hoang manh)) cua thong cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (doi chieu)) sach - ((hanh manh) OR (hoang manh)) cua thong cong dan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (doi chieu)) sach - ((hanh manh) OR (hoang manh)) cua thong cong dan than cau*".
