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