Quickstart with the Ruby API client

Supported platforms

The Algolia Ruby API client requires Ruby version 2.2 or later.

Install

Install the Ruby API client using RubyGems:

1
gem install algolia -v '~>2.0'

If you’re using bundler, add algolia as a dependency:

1
bundle add algolia --version='~> 2.0'

Be sure to install algolia and not algoliasearch which is the old version of the API client. For more information, see Update the Ruby API client.

Framework integrations

Algolia provides an integration for the Ruby on Rails framework with the algoliasearch-rails gem.

Quickstart sample app

To download and run a self-contained example, see the Ruby quickstart on GitHub.

Initialize the client

To start, you need to initialize the client. To do this, you need your Application ID and API Key. You can find both on your Algolia account.

require 'algolia'

client = Algolia::Search::Client.create('YourApplicationID', 'YourWriteAPIKey')
index = client.init_index('your_index_name')

The API key displayed here is your Admin API key. To maintain security, never use your Admin API key on your frontend, nor share it with anyone. In your frontend, only use the search-only API key or any other key that has search-only rights.

Push data

Without any prior configuration, you can start indexing 500 contacts in the contacts index using the following code:

1

index = client.init_index('contacts')
batch = JSON.parse(File.read('contacts.json'))
index.save_objects(batch)

Configure

You can customize settings to fine-tune the search behavior. For example, you can add a custom ranking by number of followers to further enhance the built-in relevance:

1
index.set_settings(customRanking: ['desc(followers)'])

You can also configure the list of attributes you want to index by order of importance (most important first).

Algolia suggests results as you type, which means you’ll generally search by prefix. In this case, the order of attributes is crucial in deciding which hit is the best.

index.set_settings({
  searchableAttributes: [
    'lastname',
    'firstname',
    'company',
    'email',
    'city',
    'address'
  ]}
)

Once configured, you can search for contacts by attributes such as firstname, lastname, or company (even with typos):

# Search for a first name
puts index.search('jimmie').to_json
# Search for a first name with typo
puts index.search('jimie').to_json
# Search for a company
puts index.search('california paint').to_json
# Search for a first name and a company
puts index.search('jimmie paint').to_json

Search UI

Use one of Algolia’s frontend libraries to build your search UI:

However, if you don’t want to use the libraries, you can build a custom UI:

  1. Design UI components with your preferred frontend system: a search box, results display, filters, and any other desired Algolia features
  2. Send search requests with the API client
  3. Parse the JSON response from the search request and display the results in your custom UI.
