    // set a tag
    $tags = [
        'tag1' => [
            [
                'member' => "a1",
                'score' => 1
            ],
            [
                'member' => "a2",
                'score' => 2
            ]
        ],
        'tag2' => [
            [
                'member' => "a1",
                'score' => 2
            ],
            [
                'member' => "b2",
                'score' => 4
            ],
            [
                'member' => "b3",
                'score' => 3
            ]
        ]
    ];
    foreach ($tags as $tag => $item) {
        $redisTagging->set($tag, $item);
    }

    // get a tag
    $result = $redisTagging->get('tag1');

    // want page limit ?
    $result = $redisTagging->offset(0)->limit(10)->get('tag1');

    // get interset of tags
    $result = $redisTagging->offset(10)->limit(10)->type('inter')->get(['tag1', 'tag2']);

    // order ?
    $result = $redisTagging->offset(10)->limit(10)->type('inter')->order('desc')->get(['tag1', 'tag2']);

    // get hottest tags
    $result = $redisTagging->topTags(3);
