Laravel”；控制器不存在“；而路线是正确的

我正在尝试使用ajax智能搜索，

但是我的应用程序找不到我在上面的教程中使用的控制器。这是我得到的错误：

Class App''Http''Controllers''Api''ApiSearchController不存在

在谷歌上搜索了这个错误消息后，我发现它是由错误的路线引起的。但我相信我设定的路线是正确的。

这是我的路线：

Route::get('api/search', 'Api'ApiSearchController@index');

这是我的控制器：

<?php namespace App'Http'Controllers;
use App'Http'Controllers'Base'Controller;
class ApiSearchController extends Controller {
public function appendValue($data, $type, $element)
{
    // operate on the item passed by reference, adding the element and type
    foreach ($data as $key => & $item) {
        $item[$element] = $type;
    }
    return $data;
}
public function appendURL($data, $prefix)
{
    // operate on the item passed by reference, adding the url based on slug
    foreach ($data as $key => & $item) {
        $item['url'] = url($prefix.'/'.$item['slug']);
    }
    return $data;
}
public function index()
{
    $query = e(Input::get('q',''));
    if(!$query && $query == '') return Response::json(array(), 400);
    $products = Product::where('published', true)
        ->where('name','like','%'.$query.'%')
        ->orderBy('name','asc')
        ->take(5)
        ->get(array('slug','name','icon'))->toArray();
    $categories = Category::where('name','like','%'.$query.'%')
        ->has('products')
        ->take(5)
        ->get(array('slug', 'name'))
        ->toArray();
    // Data normalization
    $categories = $this->appendValue($categories, url('img/icons/category-icon.png'),'icon');
    $products   = $this->appendURL($products, 'products');
    $categories  = $this->appendURL($categories, 'categories');
    // Add type of data to each item of each set of results
    $products = $this->appendValue($products, 'product', 'class');
    $categories = $this->appendValue($categories, 'category', 'class');
    // Merge all data into one array
    $data = array_merge($products, $categories);

    return Response::json(array(
        'data'=>$data
    ));
}

}
