MongoDB find returns nothing

I'm starting learning and using MongoDB. I'm following a basic sample consisting creating a collection with one document. So I first switched to a test db using use testdb. Then I executed this command in order to insert a new document into a new collection:

db.websites.insert({ name: "homepage", _id: "http://www.html.it", tags: ["Development", "Design", "System"]});

This command returned to me: WriteResult({ "nInserted" : 1 })

Finally I wanna show the last inserted document using

db.website.find()

But, (and this is the problem), it returns me nothing!! No errors, no documents...

Any suggestions?

Thanks

As understood by @chf ,the collection name in db.website.find() command was wrong: the correct one is websites (with the s).

So the Begineer Guide contains an error.

Thanks to all and sorry for the trivial question.

apparently your insertion is correctly done (it's indicated by the output in the shell). To do your test correctly, you have to

  1. Create a collection : db.createCollection('collectionName');
  2. Use this collectionn : use collectionName;
  3. Insert some data inside : db.websites.insert({ name: "homepage", _id: "http://www.html.it", tags: ["Development", "Design", "System"]});
  4. Use the command find : db.websites.find();

To find a result, be sure you're using the correct collection before do the command find.
