• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ((ve cao) OR (va cao)) suc minh thanh tai ((dua tren) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ((ve cao) OR (va cao)) suc minh thanh tai ((dua tren) or (cua tu))".
