How to sort the data while searching according to the ratings they get and also for not those are not rated - laravel-5.7

Question

I have a project of human resource management where I want to
display the ratings and non ratings jobseekers while searching as a
employer.
I have tried this but this only gives jobseekers whose ratings has been set.
public function search(Request $request)
{
$query = $request->get('query');
if (isset($query)) {
$queryParam = explode(' ', $query);
} else {
$queryParam = null;
}
$jobseekers = JobSeekers::where(function ($que) use ($queryParam) {
if (isset($queryParam)) {
foreach ($queryParam as $queries) {
$que->orWhere('job_seekers.category', 'like', '%' . $queries . '%');
$que->orWhere('job_seekers.keywords', 'like', '%' . $queries . '%');
$que->orWhere('job_seekers.experience', 'like', '%' . $queries . '%');
}
}
})->join('ratings', 'job_seekers.id', '=', 'ratings.js_id')
->groupBy('job_seekers.id')
->select('job_seekers.id', DB::raw('AVG( ratings.rating ) AS average_rating'))
->orderBy('average_rating', 'desc')
->get();
return view('search.search_all', compact('jobseekers'));
}
I have a rating table .
Schema::create('ratings', function (Blueprint $table) {
$table->increments('id');
$table->integer('emp_id')->unsigned();
$table->integer('js_id')->unsigned();
$table->integer('rating')->unsigned();
$table->longText('description')->nullable();
$table->foreign('emp_id')->references('id')->on('employers');
$table->foreign('js_id')->references('id')->on('job_seekers');
$table->timestamps();
});
I get data of only objects whose ratings is given but not for the
datas that exists but has no rating.

Try leftJoin() instead of join().
JOIN selects only results having data in joined table.
LEFT JOIN selects all results and attach data from the joined table.
public function search(Request $request)
{
$jobseekers = JobSeekers
::when($request->get('query'), function($query) use ($request) {
$words = explode(' ', $request->get('query'));
foreach($words as $word){
$query->orWhere('job_seekers.category', 'like', '%' . $word . '%');
$query->orWhere('job_seekers.keywords', 'like', '%' . $word . '%');
$query->orWhere('job_seekers.experience', 'like', '%' . $word . '%');
}
})
->leftJoin('ratings', 'job_seekers.id', '=', 'ratings.js_id')
->groupBy('job_seekers.id')
->select('job_seekers.id', DB::raw('AVG( ratings.rating ) AS average_rating'))
->orderBy('average_rating', 'desc')
->get();
return view('search.search_all', compact('jobseekers'));
}
