Laravel form include input in action attribute

LARAVEL 5.0 PHP 5.4.45

I have a route that is shaped like this :

/app/Http/routes.php

Route::get('/clients/search/{id}', 'ClientController@searchById')->where('id', '[0-9]+');
Route::get('/clients/search/{text}', 'ClientController@searchByText')->where('text', '[a-zA-Z]');

I will not print my view here but it simply search for the exact client (case id) or the first 10 clients (case text).

Then I want to create a search form. I created the route :

/app/Http/routes.php

// Route::get('/clients/search/{id}', 'ClientController@searchById')->where('id', '[0-9]+');
// Route::get('/clients/search/{text}', 'ClientController@searchByText')->where('text', '[a-zA-Z]');
Route::get( '/clients/search', 'ClientController@search');

The controller for this route :

/app/Http/Controllers/ClientController.php

<?php    

namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use DB;

class ClientController extends Controller {
    // Controllers for the 'searchById' and 'searchByText'

    public function search() {
        return view('client.search.search', [
            'title'     =>  'Client search form',
            'title_sub' =>  ''
        ]); 
    }
}

And the view for this search form :

/ressources/view/client/search/search.blade.php

<form action="/clients/search/INPUT HERE ?" method="get">
    <div class="input-group">
        <input id="newpassword" class="form-control" type="text" name="password" placeholder="Id de client, nom, prénom, ...">              
        <span class="input-group-btn">
            <button id="button_search" class="btn green-haze" type="submit"><i class="fa fa-search fa-fw"></i></button>
        </span>
    </div>
</form>

QUESTION

How can I, before submit, pass an input as a part of my action attribute for my form ? The point is to be able to launch those kind of requests :

• /clients/search/26
• /clients/search/Mike%20%Folley
• /clients/search/Paris

So my controllers handling this route could do the job. Is there any way to do that ? Or should I go for JavaScript solution (which make me sad a bit) ?
