The method returns a document with the status of the operation. 该方法返回一个带有操作状态的文档。For more information and examples, see 有关更多信息和示例，请参阅deleteMany().deleteMany()。
The delete_many() method returns an instance of pymongo.results.DeleteResult with the status of the operation.
The com.mongodb.client.MongoCollection.deleteMany method returns an instance of com.mongodb.client.result.DeleteResult with the status of the operation.com.mongodb.client.MongoCollection.deleteMany方法返回com.mongodb.client.result.DeleteResult的一个实例，带有操作状态。
deleteMany() returns a promise that provides a result. deleteMany()返回提供结果的承诺。The result.deletedCount property contains the number of documents that matched the filter.result.deletedCount属性包含与筛选器匹配的文档数。
Upon successful execution, the deleteMany() method returns an instance of MongoDB\DeleteResult whose getDeletedCount() method returns the number of documents that matched the filter.
The delete_many() coroutine asynchronously returns an instance of pymongo.results.DeleteResult with the status of the operation.
com.mongodb.reactivestreams.client.MongoCollection.deleteMany returns a Publisher object of type com.mongodb.client.result.DeleteResult if successful. 如果成功，com.mongodb.reactivestreams.client.MongoCollection.deleteMany将返回com.mongodb.client.result.DeleteResult类型的Publisher对象。Returns an instance of 如果失败，则返回com.mongodb.MongoException if unsuccessful.com.mongodb.MongoException的实例。
Upon successful execution, the IMongoCollection.DeleteMany() method returns an instance of DeleteResult whose DeletedCount property contains the number of documents that matched the filter.
Upon successful execution, the delete_many() method returns an instance of MongoDB::DeleteResult whose deleted_count attribute contains the number of documents that matched the filter.
Upon successful execution, the delete_many() method returns an instance of Mongo::Operation::Result, whose deleted_count attribute contains the number of documents that matched the filter.
Upon successful execution, the collection.deleteMany() method returns an Observable with a single element with a DeleteResult type parameter or with an com.mongodb.MongoException.

To delete all documents that match a deletion criteria, pass a filter parameter to the delete_many() method.
The following example removes all documents from the inventory collection where the status field equals "A":
Delete All Documents that Match a Condition删除符合条件的所有文档
You can specify criteria, or filters, that identify the documents to delete. 您可以指定用于标识要删除的文档的条件或筛选器。The filters use the same syntax as read operations.筛选器使用与读取操作相同的语法。

Delete Behavior删除行为¶
Indexes索引¶
Delete operations do not drop indexes, even if deleting all documents from a collection.删除操作不会删除索引，即使从集合中删除所有文档也是如此。
Atomicity原子性¶
All write operations in MongoDB are atomic on the level of a single document. MongoDB中的所有写操作都是单个文档级别的原子操作。For more information on MongoDB and atomicity, see Atomicity and Transactions.有关MongoDB和原子性的更多信息，请参阅原子性和事务。
Write Acknowledgement写确认¶
With write concerns, you can specify the level of acknowledgement requested from MongoDB for write operations. 对于写操作，您可以指定MongoDB为写操作请求的确认级别。For details, see Write Concern.有关详细信息，请参阅写关注事项。
