Question

我已经设置了一个公开MongoDB API的Azure Cosmos数据库。
我使用mongo shell连接到数据库。
我用sample创建一个新的数据库use sample。
我用sample创建一个简单的集合db.sample.insert({})
然后我尝试运行以下查询：

db.sample.findOneAndUpdate({ foo: {"$eq":1}},{ "$set": { "bar":1}},{"sort": { "foo": 1, "bar": 1 }})

当我针对普通的MongoDB 3.2.0实例运行此命令时，查询成功完成（并匹配0个结果）。但是，在CosmosDB上会生成以下堆栈跟踪：

CosmosDB中是否存在其他普通MongoDB实例中不存在的其他查询限制？这只是一个CosmosDB错误吗？报告此类错误的适当方法是什么？

Answer 1

您没有看到错误；当前，Cosmos DB的MongoDB API不支持复合索引。您的findOneAndUpdate()应该可以找到没有sort或具有单一属性sort的工作。
