the search button is not working after I deploy

The search feature is not working after I deployed my website but it is working on my localhost. In the first picture, I am able to search for anything on my localhost and able to query any data I want. But after I deploy it online, the search feature is not working

Image 1 and Image 2

here is the full code:

    @if($products -> isEmpty())
<h3 class="text-center text-danger">Product not found</h3>
@else

<div class="container mt-5">

    <div class="row d-flex justify-content-center ">

        <div class="col-md-6">

            <div class="card">
                @foreach($products as $item)
                <a href="{{ url('product/details/'.$item->id.'/'.$item->product_slug_en ) }}">
                    <div class="list border-bottom">
                        <img src="{{asset($item->product_thambnail)}}" style="padding-right: 10px; width: 120px; height: 60px; border-right: 2px solid #eee;">
                        <div class="d-flex flex-column ml-3" style="margin-left: 10px;">
                            <span>{{$item->product_name_en}}</span>
                            <small style="margin-left: 5px;">₱{{$item->selling_price}}</small>
                        </div>
                    </div>
                </a>
                @endforeach
            </div>

        </div>

    </div>

</div>
@endif

     });
    }if(text.lengh<1){
