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