• If you are trying to use Boolean operators, they must be ALL CAPS: ((te san) OR (ke san)) ky nang cao hoi. thien van nam luc ((van thanh) OR (van tuan)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te san) or (ke san)) ky nang cao hoi. thien van nam luc ((van thanh) OR (van tuan)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((te san) or (ke san)) ky nang cao hoi. thien van nam luc ((van thanh) OR (van tuan)) vi cua triet*.
