How to apply filter with relational table using with statement

I wrote a code to filter with the relational data, but I am not getting a good result. Here is code. The parent query and with a query is working independently.

public function get(Request $request, Company $company, Survey $survey)
{
    $this->authorize('update', $survey->company);
    $search = $request->get('search');
    $query = EsAnswer::where(['company_id' => $company->id, 'survey_id' => $survey->id])
        ->orderByDesc('created_at')
        ->with(['employee'=> function ($q) use($search) {
            $q->where('first_name', 'LIKE', "%{$search}%");
            $q->orwhere('last_name', 'LIKE', "%{$search}%");
            $q->select('id', 'first_name', 'last_name');   
        }]);
    if ($request->has('start_date')) {
        $query->whereDate('created_at', '>=', $request->start_date);
    }
    if ($request->has('end_date')) {
        $query->whereDate('created_at', '<=', $request->end_date);
    }

    $answers = $query->get()->groupBy('submission_id');
        // ->paginate('100');
    return $answers;
}

when I used this

{
    "search":""
}

I am getting this response:

{
    "id": 2,
    "company_id": 1,
    "employee_id": 1,
    "survey_id": 2,
    "es_question_id": 1,
    "answer": "done",
    "submission_id": "1",
    "mark_as_read": 1,
    "created_at": "2020-08-19 12:18:25",
    "updated_at": "2020-08-26 06:55:21",
    "employee": {
        "id": 1,
        "first_name": "Baseapp",
        "last_name": "saw"
    }
}

when I tried to search by employee name which is present another table, if the data is present then data should be filtered and give a response but if the employee name or search data is not present then data should not give any response. How to deal with it?

{
    "search":"sure"
}


{
    "id": 2,
    "company_id": 1,
    "employee_id": 1,
    "survey_id": 2,
    "es_question_id": 1,
    "answer": "done",
    "submission_id": "1",
    "mark_as_read": 1,
    "created_at": "2020-08-19 12:18:25",
    "updated_at": "2020-08-26 06:55:21",
    "employee": null
}

here data is null but why parent data is showing. please help and give another idea to filter with relational data.

we use whereHas to filter in related table. so use this as like

$query = EsAnswer::with('employee:id,first_name,last_name')
        ->where(['company_id' => $company->id, 'survey_id' => $survey->id])
        ->whereHas('employee', function($query) use($search) {
            $query->where('first_name', 'LIKE', "%{$search}%")
                ->orwhere('last_name', 'LIKE', "%{$search}%");
        })
        ->orderByDesc('created_at');

this will search in your related table and return null if not found anything. and i have added elegant way to eager load data. you should check out this too.

it is using whereHas, then With :

$query = EsAnswer::where(['company_id' => $company->id, 'survey_id' => $survey->id])
    ->orderByDesc('created_at')
    ->whereHas('employee', function ($q) use($search) {
      return $q->where('first_name', 'LIKE', "%{$search}%")
      ->orwhere('last_name', 'LIKE', "%{$search}%");   
    })->with(['employee' => function ($q){
        $q->select('id', 'first_name', 'last_name');
    }]);

use whereHas() function

  $query = EsAnswer::with('employee:id,first_name,last_name')
        ->where(['company_id' => $company->id, 'survey_id' => $survey->id])
        ->whereHas('employee', function($query) use($search) {
            $query->where('first_name', 'LIKE', "%$search%")
                ->orwhere('last_name', 'LIKE', "%$search%");
        })
        ->orderByDesc('created_at');
