elasticsearch + searchkick

https://intercityup.com/blog/installing-elasticsearch-mac-os-x-10-9-mavericks-development/

point $JAVA_HOME to the Java installation path in your .bash_profile:

export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"

brew install elasticsearch

And start elasticsearch with:

elasticsearch --config=/usr/local/opt/elasticsearch/config/elasticsearch.yml

# Gemfile
gem "searchkick"

After running bundle install, we can configure the Book model to be searchable:

# app/models/book.rb
class Book < ActiveRecord::Base
  searchkick
  # ...
end

Next, we need to build the index for the Book class so that the books we already have in the database will be added to Elasticsearch. When new records are created rebuilding isn't necessary, but you have to do it whenever you change the searchkick method in your model:

rake searchkick:reindex CLASS=Book

Deployment

Searchkick uses ENV["ELASTICSEARCH_URL"] for the Elasticsearch server. This defaults tohttp://localhost:9200.

Heroku

Choose an add-on: SearchBox, Bonsai, or Found.

# SearchBox
heroku addons:add searchbox:starter
heroku config:add ELASTICSEARCH_URL=`heroku config:get SEARCHBOX_URL`

# Bonsai
heroku addons:add bonsai
heroku config:add ELASTICSEARCH_URL=`heroku config:get BONSAI_URL`

# Found
heroku addons:add foundelasticsearch
heroku config:add ELASTICSEARCH_URL=`heroku config:get FOUNDELASTICSEARCH_URL`


Then deploy and reindex:

heroku run rake searchkick:reindex CLASS=MODEL
