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