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