• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (te sach)) ky nang x hoi. hieu ve cam xuc ban ((thanh lai) OR (thanh hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (te sach)) ky nang x hoi. hieu ve cam xuc ban ((thanh lai) OR (thanh hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (te sach)) ky nang x hoi. hieu ve cam xuc ban ((thanh lai) OR (thanh hai)) cua tre*.
