• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu van cam lo va dao ((va chua) or (((gia cuc) OR (gia muc)))) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu van cam lo va dao ((va chua) OR (((gia cuc) OR (gia muc)))) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu van cam lo va dao ((va chua) or (((gia cuc) OR (gia muc)))) tre*".
