• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) nang xa hoi. hieu va ((dam thuc) OR (cam xuc)) va vanh tai cau trieu.
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) or (sac ky)) nang xa hoi. hieu va ((dam thuc) or (cam xuc)) va vanh tai cau trieu*.
