• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y danh ca hoi. hieu vu ((cham xuc) OR (chat xuc)) van hanh vi ((cau tren) OR (loai tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y danh ca hoi. hieu vu ((cham xuc) OR (chat xuc)) van hanh vi ((cau tren) or (loai tren))*".
