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