 Document properties can be set by using the set() method, or by directly manipulating the document properties.
 
-As you can see, sending a document to the server is achieved by calling the add() method on the client library's DocumentHandler class. It needs the collection name ("users" in this case") plus the document object to be added. add() will return the document id as created by the server. The id is a numeric value that might or might not fit in a PHP integer.
