Query in mongo with $in operator - mongodb

Question

I have one collection which contain documents with following structure:
array (
'_id' => new MongoId("54369e2904f7055598463483"),
'user' => '123',
'model' =>
array (
'test' =>
array (
'0' => 'test1',
'1' => 'test2',
'2' => 'test3',
),
),
)
And if I do the next query in Rock Mongo I got the results.
array(
'user' => array(
'$in' => array(
'0' => '123'
)
)
)
But if I try to fetch documents which have for example key => pair value '0' => 'test1' & '1' => 'test2' I don't get any data with the next query:
array(
'model' => array(
'test' => array(
'$in' => array(
'0' => 'test1',
'1' => 'test2',
)
)
)
)
Where I'm making mistake?
Thanks in advance

Answer 1

PHP's array/hash mixup makes your example a little hard to read and reason about. But here's what your model looks like in Mongo's native syntax (a language which makes a distinction between lists and maps):
{
"_id": ObjectId(...),
"user": 123,
"model": {"test": ["test1", "test2", "test3"]}
}
So you want to query on model.test (nested document). Using Mongo's native syntax, you'd do the following:
collection.find({"model.test": {"$in": ["test1", "test2"]})
See http://docs.mongodb.org/manual/reference/method/db.collection.find/ for more info.
