• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) lang xa hoi. nhieu viec cam thuc va trinh ((vi cua) OR (di cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) lang xa hoi. nhieu viec cam thuc va trinh ((vi cua) or (di cua)) tre".
