Usage

# index.js

var esIndex   = require('es-index-mongoose');
var mongoose  = require('mongoose');

var user = new Schema({ 
  name: String, 
  company: { 
    type: mongoose.schema.types.ObjectId, 
    ref: 'Company' 
  } 
});

user.plugin(esIndex,  {
  url: 'http://localhost:9200',
  index: 'demo',
  type: 'users',
  mapping: {
    _id: { type: "string", index: "not_analyzed" },
    ...
  },
  onIndex: function(doc, done) {
    mongoose.model('Company').findById(doc.company, function(err, company) {
      if (err || !company) {
        console.log('Fail!');
        return done();
      }
      doc.company = company;
      done();
    });
  }
});

var User = mongoose.model('User', user);

User.create({ name: 'John' }, function(error, result) {

  var query = { filter: { term: { name: 'John' } } };

  User.search(query, function(results) {
    console.log(results); // [{...}]
  });
  // or
  // curl http://localhost:9200/demo/users/_search?name=John
  // { _id: "...", name: "John" }
});

User.unindex(function() { /* dropped user type from es index */ });

User.index(function(){ /* force reindex users collection from mongo to es, update mapping */});

User.findOne({ name: 'Denis' }, function(error, user) {
  if (error || !user) return console.log(error);
  user.index(function() {
    /* force reindexed user denis from mongo to es */
  });
});
