search and return objects in arrays mongoDB - mongodb

Question

I'm using laravel-mongoDB
how can I search in attraction and blog titles and only retrieve the object, not whole record.
I've tried
[
'$match' => [
"attraction.title" =>
['$regex' => '.*' . $request- >search . '.*']
],
],
result was whole record.
for example if search is first, output should be :
[{title: "first attraction", complete: false},{title: "first blog", complete: false}]
and this is records
[attraction: [{title: "first attraction", complete: false}, {title:"second attraction",
complete: true}]
blog: [{title: "first blog", complete: false}, {title: "second blog", complete: false}]
title: "test"
type: "internal"]

Answer 1

I didn't get the result with only just query but hope it helps
$data = Model::raw(function ($collection) use ($request) {
return $collection->aggregate([
['$facet' =>
[
'attr' => [
[
'$match' => [
"attraction.title" => ['$regex' => '.*' . $request->search . '.*'],
],
],
[
'$unwind' => '$attraction'
],
[
'$project' => [
'title' => '$attraction.title',
]
],
[
'$match' => [
"title" => ['$regex' => '.*' . $request->search . '.*'],
],
]
],
'blog' => [
[
'$match' => [
"blog.title" => ['$regex' => '.*' . $request->search . '.*'],
],
],
[
'$unwind' => '$blog'
],
[
'$project' => [
'title' => '$blog.title',
]
],
[
'$match' => [
"title" => ['$regex' => '.*' . $request->search . '.*'],
],
]
]
]
],
]
);
});
$data will be like:
{
attr:[
{title:...},
{title:...}
],
blog:[
{title:...},
{title:...}
]
}
and use iterator_to_array and foreach to get final result
