Combining search GET

[#1]

We are questioning our infobox for special extensible attributes. Is there a way of combining searches for network as well as network_containers. I tried this one but doesn't work: 

curl -k1 -u userassword -X GET https://grid/wapi/v2.1/networkcontainer -d _return_fields%2B=extattrs -d *Kunde~:=name&network -d _return_fields%2B=extattrs -d *Kunde~:=_*

Goal is to get one output by questioning network as well as network containers in parralel.

Thanks in advance!

You can't search across multiple objects, but you can bundle multiple searches into a single call using the '/request' path.

e.g this will search networks and containers and return you 2 arrays with the results

(you get one array per request object)

POST /wapi/v2.3/request HTTP/1.1
Host: xxx
Authorization: Basic ---
Content-Type: application/json

[
{
   "method": "GET",
   "object": "network",
   "data": {
        "network": "10.0.0.0/24"
    }
},
{
   "method": "GET",
   "object": "networkcontainer",
   "data": {
        "network": "10.0.0.0/8"
        }
}]

Thanks for your reply! Can the /request path be used within one curl call and how could this look like (syntax)? I did not find specific information therefore. If this is not working with curl how would a alternative way look like?

THANKS!
