• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - ((((anh tang) OR (anh dang))) OR (van nang)) cua nhung cong dan thai cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - ((((anh tang) OR (anh dang))) or (van nang)) cua nhung cong dan thai cao*".
