• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly nang xa hoi. hieu ve ((cham luc) OR (cham soc)) ((vay doanh) OR (van doanh)) van cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly nang xa hoi. hieu ve ((cham luc) or (cham soc)) ((vay doanh) OR (van doanh)) van cua te*".
