Make alias to attributes

[lest]

I am interested in making alias to set of attributes, e.g. instead of writing:

first_name_or_last_name_cont

it would be great to have ability to write simply:

full_name_cont

when somewhere we defines that full_name consists of first_name and last_name

Thank you for you help! I have a deeper question.

class Article < ActiveRecord::Base
  #has attributes: title, :description
  has_many :comments
end

class Comment < ActiveRecord::Base
   #has attributes :title, :description
   belongs_to :article
end

Now I hope to simply,

keyword_cont

I want to find the keyword inside the article's title and description as well as related comment's title and description.
I have tried the following code to support searching article's title and description,

  ransacker :keyword, formatter: proc{|v| v}, splat_param: true do |parent|
    Arel::Nodes::InfixOperation.new('||', parent.table[:title], parent.table[:description])
  end

Now my questions is how to deal with OUTER JOIN with comments and search title and description on comments in ransacker definition?

Drawing right from the example I linked to earlier, check out this SO post.
