• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang mai hoi. hieu ve nam thuc va ((anh va) OR (danh di)) ((cua tre) OR (cua te))~.
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang mai hoi. hieu ve nam thuc va ((anh va) or (danh di)) ((cua tre) or (cua te))*.
