Cloudant Index Creation using node and nano.js

create_C_index.js

/*
    nano doesn't yet have support for Cloudant's new index feature, 
    but you can still do it using nano's request function.
    
    This code creates an index.
    
    To try this, first replicate the database as per
    instructions here:
    
    http://docs.cloudant.com/guides/cloudant-query.html
    
    Then install nano like so:
    
    npn install nano
    
    And then run this file (after replacing USERNAME
    and PASSWORD with your own):
    
    node create_C_index.js

    Then here's some sample code for querying:

var nano = require('nano')({ url: 'https://[USERNAME]:[PASSWORD]@[USERNAME].cloudant.com' });
var query = {
	"index": { 
		"fields": ["Person_name"] 
	}
}
var opts = { 
	path: '_index',
	db: 'movies-demo', 
	method: 'post', 
	body: query
};
nano.request(opts, function(err, result) {
	// err should be null
	console.log(err);
	// result should be { result: 'created' }
	console.log(result);
	
});
