Update a document corresponding to the record


@article = Article.first
@article.update_attribute :title, 'Updated'
# SQL (0.3ms)  UPDATE "articles" SET "title" = ?...

@article.__elasticsearch__.update_document
# 2013-11-20 17:00:05 +0100: POST http://localhost:9200/articles/article/1/_update ...
# 2013-11-20 17:00:05 +0100: > {"doc":{"title":"Updated"}}

Parameters:

  • options (Hash) (defaults to: {}) —

    Optional arguments for passing to the client

Returns:

  • (Hash) —

    The response from Elasticsearch
