您正在使用的软件包没有实现track_total_hits（搜索repo内容可以确认这一点）。但是，如果需要的话，您可以派生repo并自己添加功能。

我遇到了同样的问题，为了解决它，我创建了自己的实现，包括track_total_hits和更多......，使用回调闭包。

1.延长SearchRequestFactory

use ElasticScoutDriver\Factories\SearchRequestFactory;
use ElasticAdapter\Search\SearchRequest;
use Laravel\Scout\Builder;

class ElasticSearchRequestFactory extends SearchRequestFactory
{
    public function makeFromBuilder(Builder $builder, array $options = []): SearchRequest
    {
        $searchRequest = parent::makeFromBuilder($builder, $options);

        if ($builder->callback) {
            call_user_func($builder->callback, $searchRequest, $builder);
        }

        return $searchRequest;
    }
}

2.在AppServiceProvider中注册扩展的搜索请求工厂

public function register()
{
    $this->app->bind(SearchRequestFactoryInterface::class, ElasticSearchRequestFactory::class, true);
}

3.使用SearchRequest设置值

use ElasticAdapter\Search\SearchRequest;

//... more code

$results = Model::search($query, function(SearchRequest $request) {
    $request->trackTotalHits(true);
    return $request;
})->paginate();

//... more code
