In Select2 3.x, you can pass a function as the ajax.url option. It will be passed the current search term as the first parameter, which sounds like what you are looking for.

$element.select2({
   ...
    ajax: {
        url: function (term) {
            return '/tags/' + term;
        },
        ...
    }
});

thanks it works, but there is another parameter also appended automatically tags/search/{term}?_=1415027037653 i dont know where this number come from ?? – Veldaveleda

That's a cache-busting token that is added by jQuery. If you set cache: false in your ajax configuration, it should prevent it from being added. – Filar

no doesn't work ! i have set it to false with no luck! – Veldaveleda

My bad, you should set it to true. The default, for Select2, is false. – Filar
