• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (su sach))) OR (thu sach)) ky nang mai hoi. hieu va cam xuc va danh di cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (su sach))) or (thu sach)) ky nang mai hoi. hieu va cam xuc va danh di cua viet~".
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) OR (su sach))) or (thu sach)) ky nang mai hoi. hieu va cam xuc va danh di cua viet*.
