• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach hay) or (sach nay)) dang ((xay hoi) OR (xa hoi)). hieu ve cam vuc van khang vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach hay) OR (sach nay)) dang ((xay hoi) OR (xa hoi)). hieu ve cam vuc van khang vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach hay) or (sach nay)) dang ((xay hoi) OR (xa hoi)). hieu ve cam vuc van khang vi cua tre*".
