• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty dang xay hoi. thien van cam ((xuc ban) or (duc manh)) ((danh di) OR (xanh di)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang xay hoi. thien van cam ((xuc ban) OR (duc manh)) ((danh di) OR (xanh di)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty dang xay hoi. thien van cam ((xuc ban) or (duc manh)) ((danh di) OR (xanh di)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ty dang xay hoi. thien van cam ((xuc ban) or (duc manh)) ((danh di) OR (xanh di)) cua tre*.
