Score boost does not work with join fields

[ddddddddddddddesolate]

I have two models:

Company

class Company < ApplicationRecord
  searchable auto_index: false do
    id_prefix do
      "COMPANY#{id}!"
    end

    string :topics, multiple: true, stored: false do
      topics
    end
  end 
end

and Contact

class Contact < ApplicationRecord
  searchable auto_index: false do
    id_prefix do
      "COMPANY#{company_id}"
    end
    
    join :topics, target: Company, type: :string, multiple: true, join: { from: :id, to: :company_id }
  end
end

and when I try to make a boost by the number of topics in Contacts it does not work

topics = %w[sales marketing development]

Contact.search do
  fulltext "*:*" do
    boost(10.0) { with(:topics).all_of(topics) }
    boost(5.0) { with(:topics).any_of(topics) }
  end
  
  order_by :score, :desc
end

but with Companies all works fine.

I solved this problem locally by adding one hardcoded thing, which is score=max:

sunspot/lib/sunspot/field.rb:226

"{!join from=#{from} to=#{to} v='#{query.join(' AND ')}' score=max}"

But it would be nice if they implemented it in searchable for join with a separate parameter :)
