• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang xa hoi. hieu van lam ((xuc ban) OR (cuc ban)) hanh van ((cua tre) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang xa hoi. hieu van lam ((xuc ban) OR (cuc ban)) hanh van ((cua tre) or (su triet))".
