This section introduces how to query a document.
You must have access permissions to DMS and be logged on to the DMS console.
Select an ApsaraDB for MongoDB instance and then click Log on to Database.
After you log on to the instance, select Query Window in the top navigation bar to open the query window.
Select the database that contains the target document from the drop-down list, enter the query command in the command editing text box, and click Run (F8) to run the command.
The query result is displayed on the execution result tab page at the bottom of the query window. If you run multiple query commands, all query results are displayed on the execution result tab page in the command execution order.

The List view displays detailed information about each element, such as the data type of an element. This view also supports editing documents.
