Laravel 5 nested search query

I'm trying to make a nested search query but I get this error. I'm trying to search for a company name joined by a company_id.

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'company.name' in 'where clause' (SQL: select count(*) as aggregate from `position` where `to_date` >= 2016-06-16 and `company_id` = 123795854693734 and `title` like %searchquery% and `company`.`name` like %searchquery% and `location` like %%)

Here is my controller function

public function Search(){

    $keyword = Input::get('q');
    $location = Input::get('l');

    $data = Position::where('to_date', '>=', date('Y-m-d'))
    ->where('company_id', '=', $company_id)
    ->where('title', 'like', '%'.$keyword.'%')
    ->where('company.name', 'like', '%'.$keyword.'%')
    ->where('location', 'like', '%'.$location.'%')
    ->orderBy('from_date', 'desc')
    ->paginate(10);

    $data = array(
        'data' => $data,
    );

    return view('myview', $data);

}

The model works perfectly. But here it is anyway.

namespace App;
use Illuminate\Database\Eloquent\Model;

class Position extends Model {
    protected $table = 'position';
    protected $guarded = array("id");
    protected $hidden = array();
    protected $appends = array('local_ad');

    protected $fillable = ['title', 'company_id', 'location'];

    public function company() {
        return $this->belongsTo('App\Company', 'company_id', 'id');
    }

}
