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