What about on production level ? Elasticsearch consumes memory. How can I manage it on a 2gb aws ubuntu instance?   

I'd recommend using https://aws.amazon.com/elasticsearch-service if hosting your instances in AWS. Just be mindful and lock the security of the search instance/cluster to the EC2 instance.

curl http://localhost:9200

I got "unknown regexp options - lcalht", however, elasticsearch.log shows I had started elasticsearch fine.

what did I do wrong?

Thanks in advance

never mind of my previous comment...forget it. Sorry!

Hello,

I have cloned your code to my ubuntu 16.04 running Ruby 2.3.3 with rails 5.0.1.

Everything works except autocomplete. I got a 500 Internal Server Error.

The console in Chrome browser showed that it got a stop at line 9537 of Jquery3, It stops at the same line no mater Jquery, Jquery2, or Jquery3 

The line shows the following code as,

xhr.send( options.hasContent && options.data || null );

Any hints for me?

Thanks in advance!

elasticsearch works in my server. However, I am not sure if I need to configure it for this tutorial.

Error 500 indicates that something went wrong on the server side and it should have logged something into your application logs. Check there and if you're unable to figure it out, post the relevant section of the log please.

http://localhost:3000 works

As soon as I typed letter "i", autocomplete started to give me  some error messages.

After "iron" and search, then

Movie.search(search, where: { year: { gt: 2000 } })

is highlighted to indicate where it stopped. What is your Ruby version? I got 2.3.3, perhaps I should try your Ruby version. Thank you for looking into this!

def index
  search = params[:term].present? ? params[:term] : nil
  @movies = if search
    # Movie.where("title LIKE ? OR plot LIKE ?", "%#{search}%", "%#{search}%")
    Movie.search(search, where: { year: { gt: 2000 } })
  else
    Movie.all
  end
end

Sorry, I did not know the format would mess up like this. My email is danlideng@yahoo.com. I will send you a email about the log message if you give your email address.

Have you tried reindexing your Movie model?

You can within the console run

# BASH
rails c
# RAILS CONSOLE
Movie.reindex

or straight from Bash

rake searchkick:reindex CLASS=Movie

I cannot believe I missed reindexing. Thanks a lot! Everything is working now.

Sweet! Glad that worked!

This is a great tut and it's much appreciated. 
I would love to know how I could customize the typeahead to include users profile pictures alongside the name to the queried results.

I think that would be a fun episode to cover and definitely enough content to be its own episode.

That would be extremely informative and thank you for the response kobaltz. 

hi, the video is very excellent. But I am a new guy to ruby on rails. I clone the project from github to local. I run `rake db:create` `rake db:migrate` , it seems work well.

but when i run `rake db:seed`, errors comes.  please see the log below, can you help me to solve this problem?

And, when I visit localhost:3000/movies/new,  errors come out.  please see below, can you give some suggestion?

The RestClient appears to be returning an Unauthorized response and your seeds file isn’t taking that into consideration. Hope that helps.
