• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky sang mai hoi. hieu ve cham xuc ban hanh vi ((((cua tre) OR (cua triet))) OR (cau tren))~.
• Adding a wildcard symbol may retrieve word variants: te sach ky sang mai hoi. hieu ve cham xuc ban hanh vi ((((cua tre) or (cua triet))) or (cau tren))*.
