实现智能搜索/模糊字符串比较

I have a web page on an ASP.NET MVC application where customers search for suppliers. The suppliers capture their own details on the website. The client wants a "smart search" feature, where they could search for suppliers and find them even if the supplier spelling is "slightly different" to what is typed in the search box.I have a web page on an ASP.NET MVC application
