• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky danh van hoi. lieu va cam xuc ((((va thanh) OR (gia thanh))) OR (may tinh)) von luu tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ky danh van hoi. lieu va cam xuc ((((va thanh) or (gia thanh))) or (may tinh)) von luu tre*.
