how to get all the parents and children of a document

I recently started working on mongodb. My simple application will have Geo hierarchy like

Continet-->Country-->Region--->Resort-->Accommodation

My data will be like this

     {

        "_id" : ObjectId("54854d5af2ef42fe7d4d2a44"),

        "name" : "Europe",

        "parent" : "",

        "type" : "Continent",

        "synonym" : "",

        "code" : "EEE"

    }

    {

        "_id" : ObjectId("54854d5af2ef42fe7d4d2a47"),

        "name" : "Bulgaria",

        "parent" : "EEE",

        "type" : "Country",

        "synonym" : "",

        "code" : "BGR"

    }

    {

        "_id" : ObjectId("54854d5af2ef42fe7d4d2a45"),

        "name" : "Albania",

        "parent" : "EEE",

        "type" : "Country",

        "synonym" : "",

        "code" : "ALB"

    }

    {

        "_id" : ObjectId("54854d5af2ef42fe7d4d2a48"),

        "name" : "Bourgas Region",

        "parent" : "BGR",

        "type" : "Region",

        "synonym" : "",

        "code" : "002682"

    }

    {

        "_id" : ObjectId("54854d5af2ef42fe7d4d2a49"),

        "name" : "Obzor",

        "parent" : "002682",

        "type" : "Resort",

        "synonym" : "",

        "code" : "002911"

    }

    {

        "_id" : ObjectId("54854d5af2ef42fe7d4d2a4a"),

        "name" : "Sunny Beach",

        "parent" : "002682",

        "type" : "Resort",

        "synonym" : "",

        "code" : "002548"

    }

    {

        "_id" : ObjectId("54854d5af2ef42fa7d4d2b3d"),

        "name" : "Hotel Park Avenue",

        "parent" : "002548",

        "type" : "Accommodation",

        "synonym" : "",

        "code" : "022548"

    }

As shown above there will be only the direct parent available in every document.

Now I have to get all the parents and children to a document with  "code" : "002548"

If I have the Resort code, i have to get all the Accommodations which have the respective resort as parent and i have to get the Destination, Country, Continent to which the resort belongs to.

I feel that there should be recursive queries to get this, I am using MongoTemplate for db operations.

Please Help me to get the best solution for this.

Take a look at these examples that discuss how to efficiently store a tree type hierarchy in MongoDB:

http://docs.mongodb.org/manual/tutorial/model-tree-structures/

Usually the method you pick will be dictated by the access pattern of your application (the types of reads and writes that you will make on the documents).
