Back button with searched records

I have a button that at the moment is just a button:

<button type="button" name="voltar" id="voltar" class="btn btn-default" style="margin-left: 30px">Cancelar</button>

$('#voltar').click(function() {

        alert('voltar');

    });

But I need it to return to the screen where all the searched records are and preferably to exact page, how would you do that?

Solved in a palatable way

header ("Location: ./ query". $ _SERVER ['QUERY_STRING']);

It's not exactly what you wanted, but it will do for now.
