why did not search combine key words in Algolia in Laravel 5.6?

working with Laravel 5.6 and mysql and Algolia search. I have been using following vehicles table for searching key words,

id  name  categoryname  brandname    model     districtname provincename
1   juy         car             toyota       121            coba        nochiga
2   gty         van             nissan    caravan       sara        juyi
3   bgh         car             bmw        520d             zenso       nayou
4   hyu         van             ford        max             mizuri      bakawa
5   nhj         car             toyota      121             nakaga      sara
6   gtr         car             toyota     corolla          wassa       nochiga
7   gtr         van             nissan     caravan      goa       jayui

this is my SearchingController function

$vehicles =  Vehicle::where('provincename', 'like', '%' . $request->get('search') . '%')-> orWhere('categoryname', 'like', '%' . $request->get('search') . '%')-> orWhere('districtname', 'like', '%' . $request->get('search') . '%')-> orWhere('brandname', 'like', '%' . $request->get('search') . '%')-> orWhere('modelname', 'like', '%' .  ->orderBy('adtype', 'DESC')->latest('updated_at') ->paginate(20);
            return view('vehicles.index', compact('vehicles'));
    }

this is work for only one key word on each columns like search car, bmw, toyota etc but when I use combine keys like bmw car , car sara it is not getting results? no any error it is generate following command no vehiclus display this is my results generated blade file

@forelse( $vehicles as $vehicule )

                <td>
                    @if( $vehicule->uploads->count() > 0 )
                        <a href="{{ route('vehicles.show', $vehicule->id) }}">
                            @php
                                $upload = $vehicule->uploads->sortByDesc('id')->first();
                            @endphp
                            <img src="/images/{{ $upload->resized_name }}" ></a>
                        </a>  

                    @else
                        This vehicule does not have any images attached.
                         <!-- <img src="/images/{{'noimage.png'}}"> -->
                    @endif
                </td>
            @empty
                <td>No vehicules to display.</td>
            @endforelse

how can I fix this problem?
