• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (thu hoach)) ky lang xa hoi. hiem he nam thuc gia thanh ve ((luu tre) OR (luy tre)).
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (thu hoach)) ky lang xa hoi. hiem he nam thuc gia thanh ve ((luu tre) or (luy tre))*.
