meteor mongodb limit return only id -

i want limit number of post query

db.posts.find({}); 

i got posts. want first 10 posts i've done this.

db.posts.find({}, {limit: 10}); 

but instead of having 10 posts, return id posts

it looks you're doing in mongo shell rather in meteor app directly. limit syntax differs between 2 environments:

mongo shell (docs):

db.posts.find().limit( 10 ) 

meteor js:

posts.find({},{limit: 10});
