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