• If you are trying to use Boolean operators, they must be ALL CAPS: ((((su sach) OR (so sach))) OR (vu khanh)) ky lang xa hoi. hieu van lam vu van thanh dai cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((su sach) OR (so sach))) or (vu khanh)) ky lang xa hoi. hieu van lam vu van thanh dai cua tuc".
• Adding a wildcard symbol may retrieve word variants: ((((su sach) OR (so sach))) or (vu khanh)) ky lang xa hoi. hieu van lam vu van thanh dai cua tuc*.
