How to add "not found" result on search data on laravel 5.8 - laravel

Question

Is there a way to add result "not found" if my data is not in the database ?
In my search button I want to add a result that: if the search doesn't conclude the data inside the defined form, the search must output data not found...
The search is working...
Here is my controller
pegawaicontroller.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\Pegawai;
class pegawaicontroller extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$pegawais = Pegawai::orderBy('id', 'ASC')->paginate(5);
return view('pegawai.index', compact('pegawais'));
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
return view('pegawai.create');
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'kategori' => 'required',
'jabatan' => 'required',
'nama_pegawai' => 'required',
'alamat' => 'required',
'gambar_pegawai' => 'required'
]);
// upload file
$filename = time() . '.png';
$request->file('gambar_pegawai')->storeAs('public/images', $filename);
$pegawai = new Pegawai;
$pegawai->kategori = $request->input('kategori');
$pegawai->jabatan = $request->input('jabatan');
$pegawai->nama_pegawai = $request->input('nama_pegawai');
$pegawai->alamat = $request->input('alamat');
$pegawai->gambar_pegawai = $filename;
$pegawai->save();
// $pegawai = Pegawai::create($request->all());
return redirect()->route('pegawai.index')->with('message','Data berhasil dibuat!');
}
/**

*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
$pegawai = Pegawai::findOrFail($id);
return view('pegawai.show', compact('pegawai'));
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
$pegawai = Pegawai::findOrFail($id);
return view('pegawai.edit', compact('pegawai'));
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request

public function update(Request $request, $id)
{
$this->validate($request, [
'kategori' => 'required',
'jabatan' => 'required',
'nama_pegawai' => 'required',
'alamat' => 'required',
'gambar_pegawai' => 'required'
]);
// script delete tapii gagal
// if ($request->produk()->gambar_pegawai){
// Storage::delete('images/' . $request->produk()->gambar_pegawai);
// }
// update file
$filename = time() . '.png';
$request->file('gambar_pegawai')->storeAs('public/images', $filename);
$pegawai = Pegawai::find($id);
$pegawai->kategori = $request->input('kategori');
$pegawai->jabatan = $request->input('jabatan');
$pegawai->nama_pegawai = $request->input('nama_pegawai');
$pegawai->alamat = $request->input('alamat');
$pegawai->gambar_pegawai = $filename;
$pegawai->save();
// $pegawai = Pegawai::findOrFail($id)->update($request->all());
return redirect()->route('pegawai.index')->with('message', 'Data berhasil diubah!');
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function destroy($id)
{
$pegawai = Pegawai::findOrFail($id)->delete();
return redirect()->route('pegawai.index')->with('message', 'Data berhasil dihapus!');
}
public function search(Request $request)
{
$q = $request->input('searchpegawai');
$pegawais = Pegawai::where('nama_pegawai', 'LIKE', '%'.$q.'%')
->orWhere('alamat', 'LIKE', '%'.$q.'%')
->paginate(5);
return view('pegawai.index')->with('pegawais', $pegawais)->with('query', $q);
}
}
