• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach tu) OR (sach ty)) nang x hoi. hieu van cam duc van thanh hoi ((cua te) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach tu) OR (sach ty)) nang x hoi. hieu van cam duc van thanh hoi ((cua te) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach tu) OR (sach ty)) nang x hoi. hieu van cam duc van thanh hoi ((cua te) or (cuu tre))*".
