Laravel 5.2 LengthAwarePaginator在导航到下一页时不显示任何结果

Question

I'm using a LengthAwarePaginator which paginates the results obtained from Twitter api. The first page works just fine but as i navigate to the any other page through the paginated links, it does not give any result.

Routes:

Route::any('/search', ['uses' => 'TweetController@getSearch', 'as' => 'search']);

TweetController:

public function getSearch(Request $request)
{
    $currentPage = LengthAwarePaginator::resolveCurrentPage();

    $perPage = 6;

    $tweetArray = Twitter::getUserTimeline(['screen_name' => $request['search'], 'count' => $request['count']]);

    $tweetPerPage = array_slice($tweetArray, (($currentPage-1) * $perPage), $perPage, true);

    $tweets = new LengthAwarePaginator($tweetPerPage, count($tweetArray), $perPage, $currentPage, ['path' => $request->url()]);

    return view('tweets', ['tweets' => $tweets]);
}

tweet.blade.php:

<div class="row">
    <form action="{{ route('search') }}" method="post">
        <div class="col-md-5 col-md-offset-3">
            <div class="input-group">
                <span class="input-group-addon" id="basic-addon1">@</span>
                <input type="text" class="form-control" placeholder="Search using Twitter Handle" name="search" aria-describedby="basic-addon1">
