query_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 queries an index.
    
    To try this, first replicate the database as per
    instructions here and make sure you created an index.
    (Also check out my node.js code to create the index
    here:https://gist.github.com/jeffcogswell/1c2f06f5dcd152c055b6)

    Then install nano like so:
    
    npn install nano
    
    And then run this file (after replacing USERNAME
    and PASSWORD with your own):
    
    node query_C_index.js
 
*/
 
var nano = require('nano')({ url: 'https://[USERNAME]:[PASSWORD]@[USERNAME].cloudant.com' });
var query = { "selector": { "Person_name": "Zoe Saldana" } };

var opts = { 
	path: '_find',
	db: 'movies-demo', 
	method: 'post', 
	body: query
};
nano.request(opts, function(err, result) {
	// err should be null
	console.log(err);
	// result should be a list containing info about the movie Avatar
	console.log(result);
});
