Sunspot - Retry search on partialResults

gistfile1.rb

# Sample code using Sunspot 1.2.1 to retry a search when partialResults=true
#
# I hope this code will be somewhat deprecated in Sunspot 1.2.2, since we have to
# use instance_eval to access the otherwise inaccessible @solr_response instance variable.
#

class Post

  # ...

  searchable do
    # your Sunspot search setup
  end

  # ...

  def self.search(params={})
    
    retry_search = true
    search_count = 0
    
    while retry_search && search_count < 2
      search_count = search_count + 1
      search = Post.solr_search do
        # your search code here
      end
      solr_response = search.instance_eval("@solr_result")
      retry_search = solr_response["responseHeader"]["partialResults"] == true
      search
    end
  end

end

Just updated this gist to correct an error. You should check solr_result, not solr_response, as per Sunspot's abstract_search.rb.
