• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang xa hoi. hieu ((ve cam) OR (ve cac)) cuu ban doan ((vi cua) OR (di cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. hieu ((ve cam) or (ve cac)) cuu ban doan ((vi cua) OR (di cua)) tre".
