elasticsearch-ruby's Introduction

Elasticsearch

This repository contains Ruby integrations for Elasticsearch:

  • a client for connecting to an Elasticsearch cluster,
  • a Ruby API for the Elasticsearch's REST API,
  • various extensions and utilities.

For integration with Ruby models and Rails applications, see the https://github.com/elasticsearch/elasticsearch-rails project.

Compatibility

The libraries are compatible with Ruby 1.8.7 and higher.

The library is compatible with Elasticsearch 0.90 and 1.0 -- you have to install and use a matching version, though.

The 1.x versions and the master branch are compatible with Elasticsearch 1.x API.

To use the Elasticsearch 0.90 API, install the 0.4.x gem version or use the corresponding 0.4 branch.

Installation

Install the elasticsearch package from Rubygems:

gem install elasticsearch

To use an unreleased version, either add it to your Gemfile for Bundler:

gem 'elasticsearch', git: 'git://github.com/elasticsearch/elasticsearch-ruby.git'

or install it from a source code checkout:

git clone https://github.com/elasticsearch/elasticsearch-ruby.git
cd elasticsearch-ruby/elasticsearch
bundle install
rake install

Usage

The elasticsearch library is a wrapper for two separate libraries:

require 'elasticsearch'

client = Elasticsearch::Client.new log: true

client.transport.reload_connections!

client.cluster.health

client.search q: 'test'

# etc.

Both of these libraries are extensively documented. Please read the elasticsearch-transport and the elasticsearch-api documentation carefully.

Keep in mind, that for optimal performance, you should use a HTTP library which supports persistent ("keep-alive") connections, e.g. Patron. Just require 'patron' in your code, and the library will automatically use it as the Faraday adapter.
