• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ang xa hoi. hieu ve ((cau luc) OR (cam xuc)) ((van dinh) OR (van dich)) ve cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ang xa hoi. hieu ve ((cau luc) or (cam xuc)) ((van dinh) OR (van dich)) ve cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach tu ang xa hoi. hieu ve ((cau luc) or (cam xuc)) ((van dinh) OR (van dich)) ve cua tre*.
