Steps to reproduce

$result = [
    'hittedAfterPurge' => 0,
    'hitted' => 0,
    'missed' => 0,
];
$i = 1000;
while ($i-- > 0) {
    $expiresIn = mt_rand(40, 1000);
    $cacheKey = hash('sha256', 'some string' . $expiresIn);
    $data = ['key1' => 1, 'key2' => 2];
    $pool = new Stash\Pool(new \Stash\Driver\FileSystem);
    $pool->purge();
    if ($pool->hasItem($cacheKey)) {
        $result['hittedAfterPurge']++;
    }
    $cacheItem = $pool->getItem($cacheKey)
        ->set($data)
        ->expiresAt(new \DateTime('@' . (time() + $expiresIn)));

    $saved = $pool->save($cacheItem);
    $hasItem = $pool->hasItem($cacheKey);
    if ($hasItem) {
        $result['hitted']++;
        continue;
    }
    $result['missed']++;
}
foreach ([
             'hittedAfterPurge' => $result['hittedAfterPurge'],
             'hitted' => $result['hitted'],
             'missed' => $result['missed'],
         ] as $key => $value) {
    echo $key, ' : ', var_export($value), PHP_EOL;
}

Result

hittedAfterPurge : 351
hitted : 991
missed : 9

Purge doesn't erase items from the cache, it simply cleans up items from the filesystem that have already expired (for some backends this happens automatically and purge doesn't do anything at all).

If you want to remove everything from the cache you need to run clear instead of purge.
