无法使用 laravel 在 mongodb 数据库中搜索数据

Question

我正在尝试编写查询以在 mongodb 数据库中搜索特定查询，并且 return 这里的相关信息是我目前所做的：在 Post:

<?php 
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Jenssegers\Mongodb\Eloquent\Model;
class Post extends Model
{

use HasFactory;
protected $connection = 'mongodb';
protected $collection = 'post';
protected $fillable = [
'STATUS',
'DDC_CODE',

'TRADE_NAME',

'SCIENTIFIC_CODE',

'SCIENTIFIC_NAME',

'INGREDIENT_STRENGTH',

'DOSAGE_FORM_PACKAGE',

'ROUTE_OF_ADMIN',
'PACKAGE_PRICE',

'GRANULAR_UNIT',

'MANUFACTURER',

'REGISTERED_OWNER',

'UPDATED_DATE',

'SOURCE'
];}

在Post控制器中：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Post;

class PostController extends Controller
{

public function home() {
    $posts = Post::paginate(4);

    return view('home', compact('posts'));
}
public function search(Request $request){
    
    if(isset($_GET['query'])){
        $search_text=$_GET['query'];
        $searchs=Post::whereRaw(array('$text'=>array('$search'=> $search_text)))->get();;
        return view('search',['searchs'=>$searchs]);
    }
    else{
        return view('search');
    }
 }
}

和 search.blade.php:

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <div class="container">
        <div class="row">
            <div class="col-md-6" style="margin-top:40px">
            <h4>Search Everything</h4><hr>
            <form action="{{ route('web.search')}}" method="GET">
                <div class="form-group">
                    <label for="">Enter keyword</label>
                    <input type="text" class="form-control" name="query" placeholder="Search here...">
                </div>
                <div class="form-group">
                    <button type="submit" class="btn btn-primary">Search</button>
                </div>
            </form>
            <br>
            <br>
            <hr>
            <br>
            <table border = "1">
            <tr>
            <td>STATUS</td>
            <td>DDC_CODE</td>
            <td>TRADE_NAME</td>
            <td>SCIENTIFIC_CODE</td>
            <td>SCIENTIFIC_NAME</td>
            <td>SCIENTIFIC_CODE</td>
            <td>INGREDIENT_STRENGTH</td>
            <td>DOSAGE_FORM_PACKAGE</td>
            <td>ROUTE_OF_ADMIN</td>
            <td>PACKAGE_PRICE</td>
            <td>GRANULAR_UNIT</td>
            <td>MANUFACTURER</td>
            <td>UPDATED_DATE</td>
            <td>SOURCE</td>
            </tr>
            @foreach ($searchs as $search)
            <tr>

            <td>{{ $search['STATUS'] }}</td>
            <td>{{ $search['DDC_CODE'] }}</td>
            <td>{{ $search['TRADE_NAME'] }}</td>
            <td>{{ $search['SCIENTIFIC_CODE'] }}</td>
            <td>{{ $search['SCIENTIFIC_NAME'] }}</td>
            <td>{{ $search['INGREDIENT_STRENGTH'] }}</td>
            <td>{{ $search['DOSAGE_FORM_PACKAGE'] }}</td>
            <td>{{ $search['ROUTE_OF_ADMIN'] }}</td>
            <td>{{ $search['PACKAGE_PRICE'] }}</td>
            <td>{{ $search['GRANULAR_UNIT'] }}</td>
            <td>{{ $search['MANUFACTURER'] }}</td>
            <td>{{ $search['REGISTERED_OWNER'] }}</td>
            <td>{{ $search['UPDATED_DATE'] }}</td>
            <td>{{ $search['SOURCE'] }}</td>
            </tr>
            @endforeach
            </table>
</body>
</html>

还有路由处理程序web.php:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;

Route::get('/', function () {
     return view('welcome');
});
Route::get('view','App\Http\Controllers\PostController@home');
Route::get('/search',[PostController::class,'search'])- 
>name('web.search');

当我运行代码出于某种原因它给了我一个 MongoDB\Driver\Exception\CommandException text index required for $text query 使用的查找方法可能是错误的正确的选择是什么？连接本身也没有问题，因为 postController 运行中的 home 方法是完美的。感谢您提供任何帮助。

当您在没有查询的情况下调用页面时，缺少 $searchs 变量。您要么必须 return else 分支中的 search-view 并设置 $searchs 变量：

// ...
 else {
        return view('search',['searchs' => []);
 }

或在您的 blade 文件中添加条件：

@if(isset($searchs))
   @foreach($searchs as $search)
