• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sach y)) hang ((hai hoi) OR (hai moi)). lieu va nam xua van quan va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) hang ((hai hoi) OR (hai moi)). lieu va nam xua van quan va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) or (sach y)) hang ((hai hoi) OR (hai moi)). lieu va nam xua van quan va cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach y)) hang ((hai hoi) OR (hai moi)). lieu va nam xua van quan va cua tre*.
