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