	 Mongo mongo = new Mongo("localhost", 27017);
	DB db = mongo.getDB("relevancy_data");
	DBCollection collection = db.getCollection("relevancy");	
	
	BasicDBObject andQuery = new BasicDBObject();
	List<BasicDBObject> obj = new ArrayList<BasicDBObject>();
	obj.add(new BasicDBObject("Platform","ElasticSearch"));
	obj.add(new BasicDBObject("Enviroment", "Developer"));
	obj.add(new BasicDBObject("Test_name", "Search_apple"));
	andQuery.put("$and", obj);
 
	System.out.println(obj.size());
	//System.out.println(andQuery.toString());
 
	DBCursor cursor = collection.find(andQuery);

	while (cursor.hasNext()) {
		System.out.println("inside of while");
		System.out.println(cursor.next());
	}
		System.out.println("outside of while");
