        $(document).ready(function(){

         fetch_customer_data();

         function fetch_customer_data(query = '')
         {
          $.ajax({
           url:"{{ route('list_department') }}",
           method:'GET',
           data:{query:query},
           dataType:'json',
           success:function(data)
           {
            $('tbody').html(data.table_data);
           }
          })
         }

         $(document).on('keyup', '#search', function(){
          var query = $(this).val();
          fetch_customer_data(query);
         });
        });

</script>
@endsection

here is my route file

Route::get('list-department', 'DepartmentController@listDepartment')->name('list_department');

Here is my code in controller file

  public function listDepartment(Request $request)
    {
        $listOfDepartment = Department::all();  

        if($request->ajax())
        {
            $output = '';
            $query = $request->get('query');
            if($query != '')
            {
                $data = Schema::table('department')
                    ->where('nameOfDepartment', 'like', '%'.$query.'%')
                    ->orWhere('createdBy', 'like', '%'.$query.'%')
                    ->get();
            }
            else
            {
                $data = Schema::table('department')
                    ->orderBy('nameOfDepartment', 'asc')
                    ->get();
            }

            $total_row = $data->count();
            if($total_row > 0)
            {
                foreach($data as $row)
                {
                    $output .= '<tr>
                    <td>'.$row->nameOfDepartment.'</td>
                    <td>'.$row->createdBy.'</td>
                    </tr>';
                }
            }
            else
            {
                $output = '
                <tr>
                    <td align="center" colspan="5">No Data Found</td>
                </tr>
                ';
            }
                $data = array(
                'table_data'  => $output,
                'total_data'  => $total_row
                );
                echo json_encode($data);

            }
        return view('pages.department', compact('listOfDepartment'));
    }

the issue is that whatever I wrote in search bar it now give any output.

You can use jquery contains which returns every string which is its inside

 $(document).ready(function(){
     var string =  'Any string';
     jQuery.expr[":"].Contains = jQuery.expr.createPseudo(function(arg) {
       return function( elem ) {
       return jQuery(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
     };
    });
    jQuery("tr").hide()//It will hide all the tr elements
    jQuery('tr:Contains("'+ string +'")').show();//then will show only tr which has the string
});

I have made this algorithm and also used this
