• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang cao hoi. hieu ((((vu cham) OR (va cham))) OR (van chat)) hoc va thanh via cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang cao hoi. hieu ((((vu cham) OR (va cham))) or (van chat)) hoc va thanh via cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang cao hoi. hieu ((((vu cham) OR (va cham))) or (van chat)) hoc va thanh via cua triet*.
