• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thue nang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) ((van hanh) OR (van thanh)) vai cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thue nang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) ((van hanh) or (van thanh)) vai cua su".
