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