title: Node JS Couchbase Module - How to Get All Keys of a Bucket?
body: <p>I installed the Node Couchbase client module using <code>npm install couchbase</code>. How to get the all keys (or documents) data of a bucket? 
  <p> For example, I have a bucket called <code>users</code>, and each document is a username of each individual user, so I want to retrieve the information of all of them?
  <p>Thanks</p>
