• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu van ((((cac tuc) OR (cac tac))) OR (cac tu)) van doanh vang cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu van ((((cac tuc) OR (cac tac))) or (cac tu)) van doanh vang cua triet*".
