How to do blurry search key name recursively in jq - jq

Question

I don't like the original inspect method to search specific field on Docker, so I use jq to find the config I want, for example:
docker inspect test | jq '.[].NetworkSettings
docker inspect test | jq '.. | .NetworkSettings? | objects'
both scripts can get the results:
{
"Bridge": "",
"SandboxID": "4951989910db53c8bb8368add9ddcdf0e69cd14a9ff09ef95402850f24c5de08",
"HairpinMode": false,
"LinkLocalIPv6Address": "",
"LinkLocalIPv6PrefixLen": 0,
"Ports": {},
"SandboxKey": "/var/run/docker/netns/4951989910db",
"SecondaryIPAddresses": null,
"SecondaryIPv6Addresses": null,
"EndpointID": "",
"Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"IPAddress": "",
"IPPrefixLen": 0,
"IPv6Gateway": "",
"MacAddress": "",
"Networks": {
"test_default": {
"IPAMConfig": null,
"Links": null,
"Aliases": [
"f3df83d51385",
"test"
],
"NetworkID": "4b09f5c3a82cb7c9770efec1fc818eb071cf707bd60ec96202664d5282d73b6c",
"EndpointID": "",
"Gateway": "",
"IPAddress": "",
"IPPrefixLen": 0,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"MacAddress": "",
"DriverOpts": null
}
}
}
but is base on I totally type the config name NetworkSettings correctly, is there a way to do blurry search key recursively and case insensitive by jq? like docker inspect test | jq '.. | search(. | match("network";"i") | objects', it won't work, just an example.

With this def:
def blurry($f):
($f | ascii_upcase) as $ucf
| to_entries[]
| select((.key|ascii_upcase) == $ucf)
| .value;
you could write:
.. | blurry("NetworkSettings")? | objects
Blurrier
Blurriness having many shades, you could go further, e.g.:
def veryBlurry($f):
($f | ascii_upcase) as $ucf
| to_entries[]
| select(.key | ascii_upcase | index($ucf))
| .value;
You could continue along this path, e.g. using regular expressions.
