• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (su sach))) OR (thu sach)) ky lang xa hoi. hieu va cac tu va thanh va cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (su sach))) or (thu sach)) ky lang xa hoi. hieu va cac tu va thanh va cau treo".
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) OR (su sach))) or (thu sach)) ky lang xa hoi. hieu va cac tu va thanh va cau treo*.
