• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach tu) OR (sach thu)) dang xa hoi. hieu ve cam luc va dinh vai ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tu) OR (sach thu)) dang xa hoi. hieu ve cam luc va dinh vai ((cuu tre) or (cau treo))".
