Querying Data in Pages

Nova APIs allow users to query data using search criteria. The limit and marker parameters are added to the URL of the list request to enable the system to display query results in pages. The query results are displayed by creation time (create_time) of the records in ascending order. If the creation time is not provided, the results are displayed by object ID in ascending order.
