• If you are trying to use Boolean operators, they must be ALL CAPS: ((((su sach) OR (so sach))) OR (vu sach)) ly lang xa hoi. hieu va cam tuc xa dan hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((su sach) OR (so sach))) or (vu sach)) ly lang xa hoi. hieu va cam tuc xa dan hai cau treo".
