• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tham nang xa hoi. hieu ve cac nuoc ((van hanh) OR (van thanh)) vi ((cua cu) OR (cua chu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tham nang xa hoi. hieu ve cac nuoc ((van hanh) OR (van thanh)) vi ((cua cu) or (cua chu))".
• Adding a wildcard symbol may retrieve word variants: te sach tham nang xa hoi. hieu ve cac nuoc ((van hanh) OR (van thanh)) vi ((cua cu) or (cua chu))*.
