只是在想，我应该怎么我的文档模型，这种情况下你的意见。大多重映射+减少或进行非标准化计数字段
目前我似乎有一个复杂的MultiMap索引，它从几个其他文档集合中提取计数器/统计信息，在我的开发机器上，它返回了80ms以下的测试数据的一小部分（我很满意）。
什么是性能将是这个时候我去生产服务器上一样，平均每个组合将每周收到约500次，每周200个下载和顶，收藏和评论了一把。我将每页显示20-25个混音。
你保留这个设计，也将是更好的非规范化我的柜台，并将其存储在音频文件，使用索引会少了很多工作，只要它会执行好不好？

意想不到的回答再次感谢你丹尼尔。期待Facet的方法写出来...但是目前的周计数器'出现'在地图/缩小指数中工作正常，但我会听取您的建议。 – 2012-01-27 10:24:56
