Facebook Graph Api Insights Filter Usage Parameters

Question

For filteringparam, This page is unmounted, INand CONTAIN,

https://developers.facebook.com/docs/marketing-api/insights/v2.4#filtering

curl -G \
-d "filtering=[{'field':'adgroup.delivery_info','operator':'IN','value':['archived']}]" \
-d "access_token=<ACCESS_TOKEN>" \
"https://graph.facebook.com/<API_VERSION>/act_<AD_ACCOUNT_ID>/insights"

curl -G \
-d "filtering=[{'field':'adcampaign.name','operator':'CONTAIN','value':'18-25'}]" \
-d "access_token=<ACCESS_TOKEN>" \
"https://graph.facebook.com/<API_VERSION>/act_<AD_ACCOUNT_ID>/insights"

But the information is very limited. Where can I find additional usage information filtering? for example. How should it be if I want to filter out all elements with empty (advertising campaigns) names? Or only elements with some attr (any type, for example, dict or array) are not empty (undefined).
