  "statuses":  [],

    "refresh_url": "?since_id=420290345209847808&q=http%3A%2F%2Fwww.huffingtonpost.com%2F2012%2F01%2F11%2Fgirl-scout-cookie-boycott-transgender_n_1199260.html&result_type=recent&include_entities=1",
    "count": 15,
    "since_id": 0,
    "since_id_str": "0"
  }
}

statuses为count时，15如何为空？通过基于Web的搜索表单进行相同的搜索会产生大量结果。
