I suggest a different approach.

On your controller, change it to this:

public function advancedsearch(Request $request) {

$suboptions2 = request->suboptions ? request->suboptions : null;
$min_price = request->min_price ? request->min_price : null;
$max_price = request->max_price ? request->max_price : null;
$brands2 = request->brands ? request->brands : null;

$query = Product::select('field_1', 'field_2', 'field_3')
->join('brands as b', 'b.id', '=', 'products.brand_id')
...(others joins);

// here we do the search query
if($suboptions2){
    $query->where('suboptions_field', '=', $suboptions);
}

if($min_price && $max_price){
    $query->where(function($q2) {
                $q2->where('price', '>=', $min_price)
                    ->where('price', '<=', $max_price)
            });

}

if($brands2){
    $query->where('products.brand_id', '=', $brands2);
}

// others queries

// finish it with this
$query->get();

return view('front.advancesearch', compact('products', 'brands', 'options'));

I find doing it this way is very useful because it can be really easy to implement additional queries.
