• If you are trying to use Boolean operators, they must be ALL CAPS: ((((su sach) OR (so sach))) OR (vu sach)) ky tang ma hoi. hieu van cam xuc van tuan thai cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((su sach) OR (so sach))) or (vu sach)) ky tang ma hoi. hieu van cam xuc van tuan thai cua tu~".
• Adding a wildcard symbol may retrieve word variants: ((((su sach) OR (so sach))) or (vu sach)) ky tang ma hoi. hieu van cam xuc van tuan thai cua tu*.
