sir - first of all thanks for a very good tutorial

i have a question here .

when we inserted the document (that you are showing in the beginning of this video) in the previous video, we did as a one row.
so i was thinking it will be assigned under 1 id.

i mean whole array object will be under 1 ID.

if any one get problem, use as follows.
when inserting -
db.mycol.insert({"name":"foo", "age":NumberInt(15)})

when query -
db.mycol.find
({
"age":{$gt:8}
})
