title: Using LINQ to SQL to search entire database
body: <p>Is it possible with LINQ to SQL to search the entire database (obviously only the parts that are mapped in the .dbml file) for a string match? I'm trying to write a function that will take a string of "Search Term" and search all mapped entities and return a List(Of Object) that can contain a mixture of entities i.e. if I have a table "Foo" and table "Bar" and search for "wibble", if there is a row in "Foo" and one in "Bar" that contain "wibble" i would like to return a List(Of Object) that contains a "Foo" object and a "Bar" object.
  Is this possible?</p>
