Laravel 4: uniqueness check (database) several where items

The laravel 4 documentation mentions a unique field check. They explain here how to include unique verification offers. A separate WHERE clause for a unique table, for example:

$validator = Validator::make(
    array(
        'name' => 'John Doe'
    ),
    array(
        'name' => 'unique:table,field,NULL,id,field1,value1'
    )
);

Now I assume this does something like:

"SELECT id FROM table WHERE field = 'John Doe' AND field1 = value1 LIMIT 1"

Then check if this query returns a result, and if it did not pass the test.

So, I was wondering if there is a way to add more suggestions? And if so, how?
