البحث

// Basic search
$articles = Article::search('laravel tutorial')->get();

// With filters
$articles = Article::search($query)
    ->where('author_id', $authorId)
    ->orderBy('published_at', 'desc')
    ->paginate(20);

// Advanced query
$articles = Article::search($query, function ($client, $body) {
    $body['query']['bool']['must'][] = [
        'range' => ['published_at' => ['gte' => 'now-30d']]
    ];
    return $client->search(['index' => 'articles', 'body' => $body]);
})->get();

يوفّر Elasticsearch نتائج بحث سريعة وذات صلة على نطاق واسع.
