• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang ((((o hoi) OR (co hoi))) OR (x ho)). hieu van lam xuc va hanh dinh cuu treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang ((((o hoi) OR (co hoi))) or (x ho)). hieu van lam xuc va hanh dinh cuu treo".
