Question

I’m trying to do a priority “order by” on a multiple-value field using solr – any idea how I can accomplish the below?

searchable do
  integer :skill_ids, :multiple => true
end

def self.filter_using_solr(opts={})
  Sunspot.search(JobApplication) do |s|
    opts[:order_skill_ids].each do |skill_id|
        s.order_by(:skill_ids, skill_id)
      end
    end
  end
end

I get the following exception “skill_ids cannot be used for ordering because it is a multiple-value field” – but not sure on the alternate path.

Perhaps what you’re looking for is Solr’s faceted search.

There are several posts on this subject including How do I set up a facet search with a many to many relationship using Sunspot?

Naturally, the Solr docs are also useful.
