我尝试编写搜索代码，这是我的代码：

$services = Service::query()->with('plans')->latest();


    if ($request->service_name) {
               $services = $services->whereRaw("CONVERT(JSON_EXTRACT(name, '$.ar') using 'utf8') LIKE  '%$request->service_name%' ")
                ->orWhereRaw("CONVERT(JSON_EXTRACT(name, '$.en') using 'utf8') LIKE  '%$request->service_name%' ")
                ->orWhereRaw("CONVERT(JSON_EXTRACT(name, '$.he') using 'utf8') LIKE  '%$request->service_name%' ");     
    }

        if ($request->plan_name) {
            $plan_name = $request->plan_name;
            $services = $services->whereHas('plans', function ($q) use ($plan_name) {
                $q->where('name->en','Like','%'.$plan_name.'%');
            });
       }

        return $services->get();

但是当我在请求中发送 plan_name 时，代码按服务名称而不是计划名称进行过滤

我尝试过何时在请求中发送计划名称代码按计划名称过滤数据，但它不起作用
