• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (cac ky)) nang xa hoi. hieu ve cac xuc va thanh ((tai cua) OR (tri cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (cac ky)) nang xa hoi. hieu ve cac xuc va thanh ((tai cua) OR (tri cua)) triet".
