**To create a dynamic thing group** The following ``create-dynamic-thing-group`` example creates a dynamic thing group that contains any thing with a temperature attribute that is greater than 60 degrees. You must enable AWS IoT fleet indexing before you can use dynamic thing groups. :: aws iot create-dynamic-thing-group \ --thing-group-name "RoomTooWarm" \ --query-string "attributes.temperature>60" Output:: { "thingGroupName": "RoomTooWarm", "thingGroupArn": "arn:aws:iot:us-west-2:123456789012:thinggroup/RoomTooWarm", "thingGroupId": "9d52492a-fc87-43f4-b6e2-e571d2ffcad1", "indexName": "AWS_Things", "queryString": "attributes.temperature>60", "queryVersion": "2017-09-30" } For more information, see `Dynamic Thing Groups <https://docs.aws.amazon.com/iot/latest/developerguide/dynamic-thing-groups.html>`__ in the *AWS IoT Developers Guide*.
