has_many :users
end
Companies_controller.rb
class CompaniesController < ApplicationController
respond_to :html, :xml, :json
before_action :set_company, only: [:show, :edit, :update, :destroy]
# load_and_authorize_resource
........
def recruiters
#search = Company.search(params[:q])
#companies = #search.result.includes(:users)
#user = current_user
#company = #user.company
end
end
routes.rb
Rails.application.routes.draw do
resources :companies do
resources :comments, only: [:create, :destroy]

get 'recruiters'
end
end

end
end
recruiters.html.erb (views file):
<%= search_form_for #search, url: recruiters_company_path do |f| %>
<div>
<h3>gender</i></h3>
<ul>
<% CategoryGender.all.each do |gender| %>
<li>
<%= check_box_tag('q[category_gender_name_eq_any][]', gender.name) %>
<%= gender.name %> (<%= gender.users.count %>)
</li>
<% end %>
</ul>
</div>
<button><%= f.submit 'search' %></button>
<% end %>

Answer 1

Since you are searching for Users. Then, .ransack method should be called on User model and not on Company model.
Try the following in your recruiters method:
def recruiters
#company = Company.find(params[:id])
#users = User.ransack(params[:q]).result.where(company: #company)
#user = current_user
end
1st line: I used #company = Company.find(params[:id]) instead of #company = #user.company because you are using resources pathing for Company, in which recruiter method is a "member" of (as you defined in your routes.rb).
The problem with #user.company is that say for example a user browses /companies/1/recruiters, the #company that will be assigned is going to be the same as when browsing /companies/3/recruiters. But by convention, #company in these two paths should already be different because of the id changing.
2nd line: I just added a the predicate .where(company: #company) so that the results will be filtered to the respective company.
Then in your recruiters.html.erb view file, you could just add something like the following:
...
...
<% #users.each do |user| %>
<%= user.name %>
<% end %>
...
