• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - hoang ((((sinh cua) OR (manh cua))) or (sinh va)) thong cong van thanh cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hoang ((((sinh cua) OR (manh cua))) OR (sinh va)) thong cong van thanh cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hoang ((((sinh cua) OR (manh cua))) or (sinh va)) thong cong van thanh cao*".
