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