• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dong mau hoi. hieu ve ((cam truc) OR (lam truoc)) va ((hanh tai) OR (van tai)) cuu tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky dong mau hoi. hieu ve ((cam truc) or (lam truoc)) va ((hanh tai) or (van tai)) cuu tre*.
