• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (doc sach)) ky nang ma hoi. hieu ve cham xuc va thanh vi ((cuu tre) OR (va trien))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (doc sach)) ky nang ma hoi. hieu ve cham xuc va thanh vi ((cuu tre) or (va trien))~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (doc sach)) ky nang ma hoi. hieu ve cham xuc va thanh vi ((cuu tre) or (va trien))*.
