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