• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) nang lai hoi. hieu ve chat luc va ((hanh le) OR (hanh de)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach ty)) nang lai hoi. hieu ve chat luc va ((hanh le) OR (hanh de)) cua tre".
