Linq "Sounds Like" queries on SQL using SoundEx / SoundCode

Using .NET 4 and Entity Framework it's quite easy to add "sounds like" query functionality using SQL's underlying SOUNDEX function.

The key is to use the SqlFunctions object found in System.Data.Objects.SqlClient, e.g.

var query = dataContext.Agencies.AsQueryable();

if (!string.IsNullOrEmpty(searchTerm))
{
   query = query.Where(agency => agency.Name.Contains(searchTerm) || SqlFunctions.SoundCode(agency.Name) == SqlFunctions.SoundCode(searchTerm));
}
