Pagination doesn't work after perform search

I have a form in Laravel. I used pagination in this form and search option too. Pagination works fine when I didn't search anything. If I search something which has records more than 10 (my pagination record limit is 10), it shows result perfectly in first page but in second page or third page it shows the records of whole database. It's ignore the search criteria.

Controller Code:

public function index()
{
    if (Input::has('invoiceNumber')) {
        $invoiceNumber = Input::get('invoiceNumber');
        $invoices = Invoice::where('invoiceNumber','like', '%'.$invoiceNumber.'%')->orderBy('date','desc')->paginate(10);
    } elseif (Input::has('client')) {
        $client = Input::get('client');
        $invoices = Invoice::where('client','like', '%'.$client.'%')->orderBy('date', 'desc')->paginate(10);
    } elseif (Input::has('startDate') && Input::has('endDate')) {
        $startDate = Input::get('startDate');
        $endDate = Input::get('endDate');
        $invoices = Invoice::whereBetween('date', [$startDate, $endDate])->orderBy('date', 'desc')->paginate(10);
    } elseif (Input::has('startDate')) {
        $startDate = Input::get('startDate');
        $invoices = Invoice::where('date', $startDate)->orderBy('date', 'desc')->paginate(10);
    } elseif (Input::has('endDate')) {
        $endDate = Input::get('endDate');
        $invoices = Invoice::where('date', $endDate)->orderBy('date', 'desc')->paginate(10);
    } else {
        $invoices = DB::table('invoices')
            ->join('vehicles', 'invoices.vehicle', '=', 'vehicles.registration')
            ->select(
                'invoices.*',
                'vehicles.brand',
                'vehicles.model',
                'vehicles.seat',
                'vehicles.remarks'
            )
            ->orderBy('date', 'desc')
            ->paginate(10);
    }
    return view('invoice.index',compact('invoices'));
}

After performing search my URL look like this:
