我的mongodb集合中有288个结构相似的文档。   我需要得到明确的字段campaignId，其中＆＃34;值＆＃34;数组包含   ＆＃34;再营销| Facebook |转换| 2017年2月14日＆＃34;价值（可能是   Values数组的任何元素，现在我正在考虑第一个   一个）。

到目前为止，我所做的是，

db.adsets.aggregate([
                        {$match:{Values:"Lookalike | Facebook | Conversions | 02-14-2017"}},
                        {$project:{_id:0,Values: 1}},
                        {$unwind:"$Values"},
                        {$group:{_id:"$Values",count:{$sum:1}}},
                        {$project:{_id:0,Values:1,count:1}}
                    ]);

你可以尝试这样的事情。这将为您提供在Values数组中至少有一个元素匹配条件的文档计数。

db.collection.count({Values:"Lookalike | Facebook | Conversions | 02-14-2017"}})

更新

db.collection.distinct("CampaignId", {Values:"Lookalike | Facebook | Conversions | 02-14-2017"}).length;

计算不同数量的CampaignId，其中数组包含mongodb集合中的特定值
