Step 1 – Install elasticsearch

If you haven’t installed elasticsearch on your local development machine, this article tells you how to do so in Linux

Step 2 – Add the right ruby gems for the Ruby elasticsearch client in your Gemfile and bundle install

Step 3 – Configure indexes in your Rails model(s)

Step 4 – Create / refresh the index

Start up the rails console in development mode and issue the following
commands:

These commands will setup a search index with your desired configuration in the User model above. If you ever change your settings, you’ll need to reissue these commands. I hope to come back and update these instructions with a more automated process soon.

Choosing the query type

In the User model, I called the search method on the User model to return 20 results (see the size: 20 setting). The _all keyword tells elasticsearch to match all documents using the query search_words and “or” logic. For example if search_words is “Joe Smith”, elasticsearch searches for documents with the words Joe OR Smith. The query I use above should provide you what you need for simple searches.
