如何提高我的收藏表现？

Question

在我的收藏中，我应该为我的所有字段创建一个索引，还是为文档中的每个字段创建一个索引？

我的收藏：

 {
   "_id": ObjectId("53bfb3cd4109e65f728b4b53"),
   "id_client": NumberLong(8667554),
   "id_page": NumberLong(87664),
   "id_campagne": NumberLong(646545),
   "id_application": NumberLong(987987987987),
   "id_groupe": NumberLong(2),
   "year": NumberLong(2014),
   "month": NumberLong(7),
   "day": NumberLong(11),
   "hour": NumberLong(8),
   "uid": NumberLong(78658765),
   "is_new_fan": NumberLong(0),
   "creation_time": NumberLong(1405069193),
   "is_player": NumberLong(1),
   "total_request": NumberLong(0),
   "total_share": NumberLong(0),

   "25_34": NumberLong(0),
   "35_44": NumberLong(0),
   "45_54": NumberLong(0),
   "55_64": NumberLong(0),

   "optin": NumberLong(0),
   "optin_partner": NumberLong(0),
   "custom_field_1": "Guitares",
   "custom_field_2": "NR",
   "custom_field_3": "NR",
   "univers": NumberLong(1) 
}

以下是1个字段的1个索引的例子：
