How to find all by key?

Could you please help me how to **find all** `condition` nodes recursively?


JSON example:
```json
{
"WHERE": {
"AND": [
{
"condition": {
"AND": [
{
"condition": {
"name": "cond1"
}
},
{
"condition": {
"name": "cond2"
}
}
],
"name": "cond-group"
}
},
{
"condition": {
"name": "cond3"
}
},
{
"condition": {
"name": "cond4"
}
}
]
}
}
```

I would like to find all `conditions` no matter where it is. Probably it should looks like `*[?condition]` or `values(*)[?condition]`(non-rooted expressions).
