我有一个mongo数据样本，如下所示

{
    "_id" : ObjectId("5ac70a54306dfa497877de85"),
    "type" : "activity-full",
    "data" : {
        "processDefinitionId" : "myProcess:1:4",

        "userId" : "any"
    }
}

我想要做的是基本上找到与processInstanceId相关的所有数据[流程实例ID和输出的输入数组具有包含流程实例ID的记录]。 processInstanceId id派生自process-instance-end类型。我想在一个mongo查询中执行此操作。 Mongo数据库专家可以帮助我。

答案 0 :(得分：0)

听起来你想要做的只是为一个processInstanceIds数组执行FIND，而不是逐个查找它们。如果是这样的话，请点击这里：

db.getCollection('CollectionName').find({"data.processInstanceId": {$in: ["33","2505"]}})

这将返回该数组中包含processInstanceId的所有文档[＆＃34; 33＆＃34;，＆＃34; 2505＆＃34;]。
