• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (((su sach) OR (so sach)))) ky nang xa hoi. hieu viec cac co van anh vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (((su sach) OR (so sach)))) ky nang xa hoi. hieu viec cac co van anh vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (((su sach) OR (so sach)))) ky nang xa hoi. hieu viec cac co van anh vai cuu tre*.
