For e.g. the attached file contains four helper routines to quickly look at a mo…

sw.js

//
// A bunch of functions to explore the small world database. This is
// meant to be loaded into the mongo shell so that objects can be
// explored with minimal typing .
//
// Usage: There are two ways to use this:
//
// 1. Eval the script at mongo launch time itself:
//
//    $ mongo sw.js --shell
//
// 2. Load the file after you have started the shell (this assumes you
//    are in the same location as the script file.
//
//    > load('sw.js')
//    

function getId (x) {
    db = connect("localhost:27017/smallworld");
    return db.sw_collection.find({'_id' : ObjectId(x)});
}

function getId_p (x) {
    db = connect("localhost:27017/smallworld");
    return db.sw_collection.find({'_id' : ObjectId(x)}).pretty();
}
