• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ly) OR (sach ty)) hang xa hoi. hieu va ((cham luc) OR (cham soc)) ca dan cua cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ly) or (sach ty)) hang xa hoi. hieu va ((cham luc) OR (cham soc)) ca dan cua cua viet*".
