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