Exclude draft articles from Solr index with Sunspot

Question

I have an indexed model called Article and I don't want solr to index unpublished articles.

class Article < ActiveRecord::Base
  searchable do
    text :title
    text :body
  end
end

How can I specify that article that is not #published? should not be indexed?

Answer 1

Be sure to index the published status.

class Article < ActiveRecord::Base
  searchable do
    text :title
    text :body
    boolean :is_published, :using => :published?
  end
end

Then add a filter to your query

Sunspot.search(Article) do |search|
  search.with(:is_published, true)
  # ...
end

Answer 2

A small look into the code base of sunspot_rails reveals a method called maybe_mark_for_auto_indexing which will be added to the models that include solr. You could override that method and set @marked_for_auto_indexing based on your criteria in the specific model. Its monkey patching but can help you solve the problem. The code for ur reference is in lib/sunspot/searchable.rb.
