• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach y hang xa hoi. hieu ((ve chat) OR (van chat)) ((xuc van) OR (duc van)) hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach y hang xa hoi. hieu ((ve chat) OR (van chat)) ((xuc van) or (duc van)) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: nuoc sach y hang xa hoi. hieu ((ve chat) OR (van chat)) ((xuc van) or (duc van)) hanh vi cua tre*.
