• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang ((van hoi) OR (van hoe)). hieu van lam dung ban anh ((vai cua) OR (hai cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky lang ((van hoi) or (van hoe)). hieu van lam dung ban anh ((vai cua) or (hai cua)) tre*.
