mongodb Can't get the query to work - mongodb

Question

I'm trying to do a query in mongodb but I can't get it to work.
My document looks something like this.
{
"_id" : ObjectId("5305e54133e65b7341d63af3"),
"clients" : [
{
"aggregations" : {
"department" : [
"department1",
"department3"
],
"customer" : "customer2"
},
"lastLogin" : ISODate("2014-02-26T09:41:56.445Z"),
"locale" : "en"
"name" : "Test",
"validFrom" : null,
"validTo" : null,
"visiting" : {
"phone" : "031-303030",
"company" : "MyCompany",
"office" : [
"jag är ett test",
"lite mer data"
],
"country" : "Norge"
}
},
{
"approvedEmailSent" : true,
"lastLogin" : ISODate("2014-03-01T15:27:12.252Z"),
"locale" : "en",
"name" : "Test2",
"visiting" : {
"phone" : "031-307450",
"company" : "Other Company",
"branch" : "Advertising agency"
}
}
],
"firstname" : "Greger",
"lastname" : "Aronsson",
"username" : "TheUsername"
}
As you can see a user can have many clients. They are matched by name. The clients have visiting.company but sometimes this will not be the case.
I want to query where the clients.name is Test and regexp for visting.company and also firstname, lastname. If I'm logged in at Test2 I don't want hits on visiting.company "MyCompany". Hope this makes sense!

You can write query like :
db.visitCompany2.find({ $or : [
{'clients.name': 'Test2'}, //Company name
{'clients.visiting.company': {
$regex: /Other/g //Your visiting company regex
}},
{firstname: "Greger"},
{"lastname": "Aronsson}"
]}, {
'clients.$': 1, //projection for clients
firstname: 1,
lastname: 1
});
Output:
{
"_id": ObjectId("5305e54133e65b7341d63af3"),
"clients": [{
"approvedEmailSent": true,
"lastLogin": ISODate("2014-03-01T15:27:12.252Z"),
"locale": "en",
"name": "Test2",
"visiting": {
"phone": "031-307450",
"company": "Other Company",
"branch": "Advertising agency"
}
}],
"firstname": "Greger",
"lastname": "Aronsson"
}
