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