• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) dang van hoe. hieu van lam xuc va thanh ((di cua) OR (doi cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sac ky)) dang van hoe. hieu van lam xuc va thanh ((di cua) OR (doi cua)) triet*".
