• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang van hoi. hieu ((((ve cham) OR (vu cham))) OR (ve cac)) cuu ban danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang van hoi. hieu ((((ve cham) OR (vu cham))) or (ve cac)) cuu ban danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y lang van hoi. hieu ((((ve cham) OR (vu cham))) or (ve cac)) cuu ban danh vi cua tre*.
