• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang xa hoi. ((hieu va) OR (thien van)) cam xuc ((va dinh) OR (va kinh)) vinh cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang xa hoi. ((hieu va) or (thien van)) cam xuc ((va dinh) OR (va kinh)) vinh cau tren*".
