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