• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. ((lieu van) OR (lieu va)) cao duc va dinh vai ((cua tu) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. ((lieu van) or (lieu va)) cao duc va dinh vai ((cua tu) OR (cua tuc))".
