• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y xang xa hoi. hieu van cam xuc va ((((thanh vi) OR (thanh ve))) OR (hanh vi)) cau tren.
• Adding a wildcard symbol may retrieve word variants: tu sach y xang xa hoi. hieu van cam xuc va ((((thanh vi) or (thanh ve))) or (hanh vi)) cau tren*.
