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