Acts_as_taggable_on tag names as Thinking Sphinx attributes

My model is indexed with Thinking Sphinx and I am wanting to filter search results by the model's tags—provided by acts_as_taggable_on. I read this previous question, which enabled my searches to use :conditions => { :tags => 'Comedy' } as a filtering query.

This is not a catch-all solution, since by default all text is searched in Sphinx's indexed fields. For example, when I search Model.search :conditions => { :tags => "Comedy" }, results with the tag Black Comedy also appear. I see that using attributes instead of fields is a solution, but I cannot seem to get valid results when searching Model.search :with => { :tags => "Comedy" } and my define_index block looks like this:

define_index
   indexes title, :sortable => true
   has category_tags(:name), :as => :tags
end

Note that I am building upon the previous answer provided in the question linked above. The answerer details indexing tags within context—thus the reason for the category_tags method.

Change your index to:

define_index
  indexes title, :sortable => true
  has "CRC32(category_tags.name)", :as => :tags, :type => integer
end

Note: category_tags.name refers to your_table_name.column_name

And search the tag after converting to int:

Model.search :with => {:tags =>'Comedy'.to_crc32}
