• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (su sach))) OR (thu sach)) y nang mai hoi. hieu ve cam xuc van thanh vai cua duc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (su sach))) or (thu sach)) y nang mai hoi. hieu ve cam xuc van thanh vai cua duc*".
