• Performing a fuzzy search may retrieve terms with similar spellings: (("hoi nhap cau.") OR ((("hoi phat cau.") OR ((("hoa phat chau.") OR ("hoa phan cau."))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"hoi nhap cau.\") OR (((\"hoi phat cau.\") OR (((\"hoa phat chau.\") OR (\"hoa phan cau.\"))))))".
• Removing quotes may allow a broader search: (( hoi nhap cau. ) OR ((( hoi phat cau. ) OR ((( hoa phat chau. ) OR ( hoa phan cau. )))))).
• Adding a wildcard symbol may retrieve word variants: (("hoi nhap cau.") OR ((("hoi phat cau.") OR ((("hoa phat chau.") OR ("hoa phan cau."))))))*.
