ElasticSearch ruby client. Credit goes to my coworkers at GitHub, I just turned it into a gem.

Add to Gemfile

gem 'elasticsearch-client', :require => 'elasticsearch'

Create connection:

index = 'twitter'
url = 'http://localhost:9200'
es = ElasticSearch::Index.new(index, url)

Index a document:

type = 'tweet'
doc = {:id => 'abcd', :foo => 'bar'}
es.add(type, doc[:id], doc)

Get a document:

id = '1234'
es.mget(type, [id])

Get documents:

id2 = 'abcd'
es.mget(type, [id, id2])

Search:

query = {
  :query => {
    :bool => {
      :must => {
        :query_string => {
          :default_field => '_all',
          :query => 'foobar!',
        }
      }
    }
  }
}
es.search(type, query)

Remove record:

es.remove(type, id)

Remove by query:

es.remove_by_query(type, :term => {:foo => 'bar'})

Remove all of type:

es.remove_all(type)

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so we don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine, but bump version in a commit by itself so we can ignore when we pull)
• Send us a pull request. Bonus points for topic branches.
