• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y danh xa hoi. hieu ve cham loc ((va dauh) OR (va dau)) ((hai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y danh xa hoi. hieu ve cham loc ((va dauh) or (va dau)) ((hai cua) OR (thai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y danh xa hoi. hieu ve cham loc ((va dauh) or (va dau)) ((hai cua) OR (thai cua)) tre*.
