Multiple Elasticsearch Indexes

问题

I have a staging & production instance of a Rails 3 application (using the tire gem) on the same Ubuntu server. It appears that both of these instances are sharing the same elasticsearch index which obviously isn't what I want.

How can I get my production and staging instances to use separate instances?

You need override the index name. Assuming you're tying into ActiveRecord it will create an index name based on the model in question. You could adjust the name with a prefix like so;

class Article < ActiveRecord::Base

  include Tire::Model::Search
  include Tire::Model::Callbacks

  index_prefix "#{Rails.env}" 

  ...

which would then create an index named development_articles, production_articles etc. It's important the the index_prefix comes after the Tire includes.

Or alternatively rename the index entirely

class Article < ActiveRecord::Base

  include Tire::Model::Search
  include Tire::Model::Callbacks

  index_name "My-Development-Article-Index" 

  ...
