• If you are trying to use Boolean operators, they must be ALL CAPS: co ((sach ky) OR (sac ky)) lang xa hoi. hieu hien ((sach nuoc) OR (bach tuoc)) va dau vai cua cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "co ((sach ky) OR (sac ky)) lang xa hoi. hieu hien ((sach nuoc) or (bach tuoc)) va dau vai cua cu*".
