SOLVED

After weeks of playing with codes finally I came to the right results for myself (in my case it works this way for others maybe works with other suggested answers)

public function advancedsearch(Request $request) {
    $options = Option::all();
    $brands = Brand::all();
    $brandss = Input::has('brands') ? Input::get('brands') : [];
    $suboption = Input::has('suboptions') ? (int)Input::get('suboptions') : [];
    $min_price = Input::has('min_price') ? (int)Input::get('min_price') : null;
    $max_price = Input::has('max_price') ? (int)Input::get('max_price') : null;

    //codes
    if(count($request['suboptions'])){
      $products = DB::table('products')
      ->join('product_suboption', function ($join) {
        $suboption = Input::has('suboptions') ? Input::get('suboptions') : [];
            $join->on('products.id', '=', 'product_suboption.product_id')
                 ->where('product_suboption.suboption_id', '=', $suboption);
        })
      ->paginate(12);
    }

    elseif(count($request['brands'])){
      $products = DB::table('products')
      ->whereIn('products.brand_id', $brandss)
      ->paginate(12);
    }

    elseif(count($request['min_price']) && count($request['max_price'])){
      $products = DB::table('products')
      ->whereBetween('price', [$min_price, $max_price])
      ->paginate(12);
    }


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

NOTE: most of my pricing issues solved with (int) as you see in my codes (int)Input::get('min_price') and (int)Input::get('max_price').

Special thanks to Ravindra Bhanderi for his count($request[''] suggestion.
