Rails add two scope with active record result

I am using acts-as-taggable-on gem

i use single field to search by tag_name and user_name

User.rb

class User < ActiveRecord::Base

  acts_as_taggable
  attr_accessor: :user_name, :age, :country, tag_list
  scope :tagged_with, lambda { |tag|
    {
      :joins => "INNER JOIN taggings ON taggings.taggable_id = user.id\
               INNER JOIN tags ON tags.id = taggings.tag_id AND taggings.taggable_type = 'User'",
      :conditions => ["tags.name = ?", tag],
      :order => 'id ASC'
    }
  }
  def self.search(search)
    if search
      where('name LIKE ?', "%#{search}%") + tagged_with(search)
    else
      scoped
    end
  end
end

But i have pagination issue while getting this as Array and i used "will_paginate/Array" in config/initializer/will_paginate.rb it doesn't work.

Can you help me to add this scopes as ActiveRecord relation to use pagination without issue.
