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