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