Laravel 5.1 No query results for model in queue

I am trying to learn laravel database queue from its official documentation. I have done configuration as given in documentation .

Here my jobs :

<?php

namespace App\Jobs;

use App\SearchLog;
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Bus\SelfHandling;
use Illuminate\Contracts\Queue\ShouldQueue;

class SendTicket extends Job implements SelfHandling, ShouldQueue
{
    use InteractsWithQueue, SerializesModels;

    protected $log;

    protected $searchLog = array();



    public function __construct(SearchLog $log , $data = array())
    {
        $this->log = $log;
        $this->searchLog = $data;
    }

     /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {

      $this->log->create($this->searchLog);     
    }

In my controller I call like this

public function store(Request $request)
{
 $searchLog = array();
 // searchLog contains the data to be inserted into database 
 $log = new SearchLog();
 $this->dispatch(new SendTicket($log , $searchLog));
 }

When I run the php artisan queue:listen I get the error like

[Illuminate\Database\Eloquent\ModelNotFoundException] No query results for model [App\SearchLog].

But when I edit the jobs like this

//only edited code 
public function __construct($data = array())
{
    $this->searchLog = $data;
}

/**
 * Execute the job.
 *
 * @return void
 */
public function handle()
{
  SearchLog::create($this->searchLog);   
}

And when call from like this

 public function store(Request $request)
 {
    $searchLog = array();
    // searchLog contains the data to be inserted into database 
    $this->dispatch(new SendTicket($searchLog));
 }

It works fine and the data is inserted .
Here, my question is :

1. How to send the object to the queue ?
2. What is best way to send data to queue so that we can process ?
