• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty lang) OR (tay lang)) xa hoi. hieu ve cam luc va danh ((hai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty lang) OR (tay lang)) xa hoi. hieu ve cam luc va danh ((hai cua) or (thai cua)) tre".
