php - 实现 Searchable，Laravel 的一个搜索特性

Question

我正在尝试使用 Searchable 实现可搜索功能，这是 nicolaslopezj 的 Laravel 搜索特性，我使用了以下代码。但这似乎不起作用。如果数据库中只有两条记录，它会显示记录，但如果超过两条记录，它不会搜索。

模型:Contact.php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Nicolaslopezj\Searchable\SearchableTrait;


class Contact extends Model
{
    use SearchableTrait;

        protected $searchable = [
        'columns' => [
            'contacts.first_name' => 10,
            'contacts.last_name' => 10,
        ]];
}

Controller :搜索 Controller

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Nicolaslopezj\Searchable\SearchableTrait;
use View;
use App\Contact;
use App\Tag;
use App\Project;
use App\User;
//use Illuminate\Support\Facades\Input;

class SearchController extends Controller
{
    public function findContact(Request $request)
        {
            return Contact::search($request->get('cname'))->get();
        }

         public function contactPrefetch()
        {
           $all_contacts= Contact::All();
           return \Response::json($all_contacts);
        }
}

查看:show.blade.php

                },
                datumTokenizer: Bloodhound.tokenizers.whitespace('cname'),

                                   },

                    suggestion: function (data) {

路线:

Route::get('find_contact', 'SearchController@findContact');
Route::get('find_contact_all', 'SearchController@contactPrefetch');
