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