• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach nha mo gioi bon thong tin ) OR ( tu sach cha me gioi cong hoang (minh OR dinh) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach nha mo gioi bon thong tin ) or ( tu sach cha me gioi cong hoang (minh OR dinh) ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach nha mo gioi bon thong tin ) or ( tu sach cha me gioi cong hoang (minh OR dinh) ))*.
