Implementing Search Feature using Searchkick, Twitter Bootstrap 4 and Rails 5

Install Elasticsearch

On Mac:

brew install elasticsearch
elasticsearch: Java 1.7+ is required to install this formula.
You can install with Homebrew Cask:
  brew install Caskroom/cask/java
  You can download from:
  Error: An unsatisfied requirement failed this build.

Java is a pre-requisite. You can install it by:

$ brew install Caskroom/cask/java
==> Tapping caskroom/cask
Cloning into '/usr/local/Library/Taps/caskroom/homebrew-cask'...

Validate ElasticSearch Installation

Use curl command in the terminal to hit the ElasticSearch server.

curl -XGET 'localhost:9200' 

You will get a JSON response.

  "status" : 200,
  "name" : "Yukio",
  "cluster_name" : "elasticsearch_bparanj",
  "version" : {
    "number" : "1.7.3",
    "build_hash" : "05d4530971ef0ea46d0f4fa6ee64dbc8df659682",
    "build_timestamp" : "2015-10-15T09:14:17Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  "tagline" : "You Know, for Search"

You can also verify the ElasticSearch server version.

Start the ElasticSearch Server

You many need to run the following command as sudo.


Add the searchkick method to the movie model.

class Movie < ApplicationRecord

Reindex the movie model.

rake searchkick:reindex CLASS=Movie

If you don't reindex after you install searchkick, you will get the error:

Searchkick::MissingIndexError in SearchController#index
Index missing - run Article.reindex

You can add:


to the Article model instead of running the rake task. This way, you don't have to run the rake task on production server. Add the search action to the movies controller.

def search
  @movies = if params[:term].present?[:term])

Add the search form to the header partial.

  <%= form_tag(search_movies_path, method: :get, class: "form-inline pull-xs-right", role: 'search') do %>
    <%= text_field_tag :term, params[:term], class: 'form-control' %>
    <%= submit_tag 'Search', name: nil, class: "btn btn-success-outline" %>
  <% end %>

Create search.html.erb.

<div class="row">
  <%= render @movies %>

Create a movie partial.

<div class="col-sm-6 col-md-5">
  <div class="thumbnail">
    <%= link_to (image_tag movie.poster.url(:medium), class: 'image'), movie %>

Reload the browser. If you get an error:

undefined local variable or method `searchkick' for #<Class:0x007f2cc8>

Restart the server. You can now search any movie, the cool thing is that even if you make a spelling mistake, searchkick is smart enough to find the movie. For better performance, add:

gem 'typhoeus'

to Gemfile. Run bundle and create an initializer with:

require "typhoeus/adapters/faraday"
Ethon.logger ="/dev/null")
