• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang cao) OR (lang xa)) hoi. lieu va cam xuc van khang ((dien cu) OR (dien tu)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang cao) or (lang xa)) hoi. lieu va cam xuc van khang ((dien cu) OR (dien tu)) triet".
