• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky lang van hoi. hieu ((viec bach) OR (viec bao)) nuoc va danh ((di cua) OR (doi cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky lang van hoi. hieu ((viec bach) OR (viec bao)) nuoc va danh ((di cua) or (doi cua)) te~".
• Adding a wildcard symbol may retrieve word variants: su sach ky lang van hoi. hieu ((viec bach) OR (viec bao)) nuoc va danh ((di cua) or (doi cua)) te*.
