Hi there,

Is there a way to get all device with a specific tag using the API?

Tryied  
`GET http://acs.server:7557/devices/?query={"Tags.sometag":"true"}`,  
It returns 200 OK with an empty array.

heres an example:  
[http://youracsserver.com:7557/devices/?query={“\_tags”:“sometag”}&projection=\_id](http://youracsserver.com:7557/devices/?query=%7B%22_tags%22:%22sometag%22%7D&projection=_id)

7557 is the default port of the NBI, depending on your setup it may be another port.

the projection=\_id makes it return just the \_id to be fast, otherwise it will return all the data from the devices, depending on how many you get, it may take a while
