Search dynamic array index MongoDB - laravel

Question

I'm relatively new to MongoDB and trying to figure out how to search for data which has dynamic keys, my dataset is below:
[
'id' => '60bb040f7e589378f644f9a2',
'name' => 'foo',
'settings' => [
'foo' => [
'type' => 'custom',
'enabled' => 'yes'
],
'bar' => [
'type' => 'custom',
'enabled' => 'no'
],
'baz' => [
'type' => 'custom',
'enabled' => 'no'
]
]
]
I want to get the search inside settings, and get all the settings which has enabled as yes.
I've tried this
return Customer::raw(function($collection) {
return $collection->aggregate([
[
'$search' => [
"wildcard" => [
'query' => 'yes',
'path' => 'settings.*.enabled'
]
]
]
]);
});
I am getting the following errror:
Unrecognized pipeline stage name: '$search'
I've also tired using $match, like this
Customer::raw(function($collection)
{
return $collection->aggregate([
[
'$match' => [
"settings.*.enabled" => 'yes'
]
],
]);
})
But it does't return any value.
Any direction on achieving this will be helpful. Thanks!

Ok this is a bit complex but is all I can come up with myself:
Customer::raw(function($collection)
{
return $collection->aggregate([
[
'$addFields' => [
"settingsArray" => [
'$objectToArray' => '$settings'
]
]
],
[
'$unwind' => [
'path' => '$settingsArray'
]
],
[
'$match' => [
'settingsArray.v.enabled' => 'yes'
]
],
[ '$unset' => 'settingsArray' ],
[
'$group' => [
'_id' => '$_id',
doc => [ '$first' => '$$ROOT' ]
]
],
[
'$replaceRoot' => [
'newRoot' => '$doc'
]
]
]);
});
This should return all documents with at least one enabled setting.
A key point about aggregation is that the pipeline works on all documents that the previous stage of the pipeline returned.
Here's the aggregation pipeline explanation:
$addFields will convert the settings object to an array of format [ { k: key, v: value } ] e.g. [ { k: 'foo', 'v': { type: 'custom', enabled: 'yes' } }, ... ]
$unwind will "unwind" the document and "replace" it with X copies of the same document one for each entry in the newly added settingsArray array. The settingsArray at this stage is not an array anymore but a single entry of type { k: key, v: value }. In short you'd get one document per setting
$match will do the actual matching for any document with an enabled setting (remember now each document will only have a single setting as settingsArray
$unset will remove the settingsArray from each document bringing it back to its original format
$group will group all documents by their _id and use the first result of each group as a doc entry. Each document will now be like { _id: <id>, doc: <original document> }
$replaceRoot will set the root of the document to doc and therefore bring the documents back to their original format.
Would love to hear if anyone else has a better solution here.
