• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach ha) OR (sach ty))) OR (sac ky)) nang ma hoi. hieu ve cam xuc va dau cua cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((((sach ha) OR (sach ty))) OR (sac ky)) nang ma hoi. hieu ve cam xuc va dau cua cuu tre*.
