• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach huy) OR (bach hue)) hoang va hoi. ((hieu van) or (hieu va)) cam luc van minh vi luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach huy) OR (bach hue)) hoang va hoi. ((hieu van) OR (hieu va)) cam luc van minh vi luu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach huy) OR (bach hue)) hoang va hoi. ((hieu van) or (hieu va)) cam luc van minh vi luu tre*".
