• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach y nang xa hoi. hieu ((((ve cam) OR (ve cham))) OR (vu cham)) duc va thanh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach y nang xa hoi. hieu ((((ve cam) OR (ve cham))) or (vu cham)) duc va thanh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: thuoc sach y nang xa hoi. hieu ((((ve cam) OR (ve cham))) or (vu cham)) duc va thanh vinh cuu tre*.
