• If you are trying to use Boolean operators, they must be ALL CAPS: te ban ky lang xa hoi. hieu va cham ((((luc van) OR (luu van))) OR (duc van)) hanh thai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ban ky lang xa hoi. hieu va cham ((((luc van) OR (luu van))) or (duc van)) hanh thai cua tre".
• Adding a wildcard symbol may retrieve word variants: te ban ky lang xa hoi. hieu va cham ((((luc van) OR (luu van))) or (duc van)) hanh thai cua tre*.
