Elastic search undefined? - node.js

Question

I used mongo-connector on my linux server
pip install mongo-connector
python mongo_connector.py -m localhost:27217 -t http://localhost:9200
Inside my local node.js server I am using mongoDB which is hosted on my linux server
var Movie = require('../models/Movie');
var mongoosastic = require("mongoosastic");
var elasticsearch = require('elasticsearch');
movie = new Movie({title: 'Warrior'});
movie.save(function() {
console.log(arguments)
Movie.search({query:"Warrior"}, function(err, results) {
console.log(results);
});
});
Schema
var mongoose = require('mongoose');
var elasticsearch = require('elasticsearch');
var mongoosastic = require("mongoosastic");
var movieSchema = new mongoose.Schema({
language: String,
year: String,
title: { type:String, es_indexed:true },
director: String
});
movieSchema.plugin(mongoosastic);
module.exports = mongoose.model('Movie', movieSchema);
I keep getting undefined. I think the data is indexed, but I can't search for it.
Testing
curl -XPUT 'http://localhost:9200/blog/user/dilbert' -d '{ "name" : "Dilbert Brown" }'
curl -XGET 'http://localhost:9200/blog/user/dilbert?pretty=true'
{
"_index" : "blog",
"_type" : "user",
"_id" : "dilbert",
"_version" : 1,
"found" : true,
"_source":{ "name" : "Dilbert Brown" }
}
The problem could be that node.js is hosted on my local machine and the mongoDB/elasticsearch is on my linux server.

Answer 1

By pointing at the fact that your node.js and ES are on two different hosts, you've probably put the finger on the issue.
Looking, at your command line :
python mongo_connector.py -m localhost:27217 -t http://localhost:9200
-m points to your Mongo DB on the localhost port 27217 (unless that port is the entry to an SSH tunnel to your remote linux server)
-t points to your replication endpoint (i.e. Elasticsearch on port 9200 of your local machine)
According to your statement that Elasticsearch and MongoDB are hosted on your remote linux server, you should replace localhost with the host name or IP address of your Linux server and make sure the ports 27217 and 9200 are open on that host.
Then you should also make sure that your Node.js and mongoosastic points to your linux server, because by default it uses localhost:9200, i.e. your local machine. So use this instead and point to your linux server:
movieSchema.plugin(mongoosastic, {
hosts: [
'your_linux_host:9200'
]
});
And also that your mongoose connection points to your linux server as well.
mongoose.connect('mongodb://your_linux_host/your_database');
