• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang xa hoi. hieu va ((cac tuc) OR (cac toc)) van ((hanh vai) OR (hanh va)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang xa hoi. hieu va ((cac tuc) OR (cac toc)) van ((hanh vai) or (hanh va)) cua triet".
