• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chieu sach) OR (chiet tach)) - hanh san cua dong cong ((dan than) or (van than)) ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (chiet tach)) - hanh san cua dong cong ((dan than) OR (van than)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chiet tach)) - hanh san cua dong cong ((dan than) or (van than)) ban*".
