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