• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) nang mai hoi. hieu ve cam duc va nhanh ((hai cua) OR (dai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) nang mai hoi. hieu ve cam duc va nhanh ((hai cua) OR (dai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) nang mai hoi. hieu ve cam duc va nhanh ((hai cua) OR (dai cua)) tre*.
