• Performing a fuzzy search may retrieve terms with similar spellings: (("te sach hoi hoa") or ((("te cach tho hoa") OR ("te cach cho hoa"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("te sach hoi hoa") OR ((("te cach tho hoa") OR ("te cach cho hoa"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"te sach hoi hoa\") or (((\"te cach tho hoa\") OR (\"te cach cho hoa\"))))*".
• Removing quotes may allow a broader search: (( te sach hoi hoa ) or ((( te cach tho hoa ) OR ( te cach cho hoa ))))*.
