如何清除URL搜索laravel？

Question

1. Search.blade.php

       <form action="{{url('search')}}" method="get" id="main_search" >
            <input type="text" name="search" id="search" placeholder=" Search Movies">
            <button type="submit"><i class="fa fa-search" aria-hidden="true"></i></button>
       </form>
   

2. 路线

    Route::get('search', ['as' => 'getSearch', 'uses' => 'SearchController@getSearch']);
   

搜索时，URL结果如下

     http://www.example.com/search?search=keyword

如何将网址转换为

     http://www.example.com/search/keyword
