• Performing a fuzzy search may retrieve terms with similar spellings: te sach y dang van hoi. hieu van cac quoc ((ban benh) or (((san benh) OR (sau benh)))) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang van hoi. hieu van cac quoc ((ban benh) OR (((san benh) OR (sau benh)))) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang van hoi. hieu van cac quoc ((ban benh) or (((san benh) OR (sau benh)))) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y dang van hoi. hieu van cac quoc ((ban benh) or (((san benh) OR (sau benh)))) vi cua tre*.
