== Setup

  will come back soon!

=== Anonymous Scopes

  scope = Offer.order("popularity desc").with(:city => "Hamburg").paginate(:page => 2, :per_page => 10)
  
  # no query sent yet
  # query is sent e.g. when
  
  scope.each { |offer| puts offer.city }                            # objects of current page are iterated
  scope.total_entries                                               # no objects loaded though
  scope.ids                                                         # no objects loaded, only ids are returned
  scope.first or scope.last                                         # all objects are loaded, only first or last in "page" is returned

=== Named Scopes

  class Offer
    named_search_scope :popular do
      order("popularity desc")
    end
    
    named_search_scope :for_artists do |ids|
      with(:artist_id => ids)
    end
  end
  
  Offer.popular.for_artists([1, 2, 3])                              # various named scopes can be combined
  Offer.popular.for_artists([1, 2, 3]).with(:available => true)     # named scopes can also be combined with anonymous scopes

=== Geo Searches
  Offer.search_scope.near(47.0, 11.0).within(1.kms)
  Offer.search_scope.near(47.0, 11.0).within(100.meters)

== Contributing to search_scopes
 
* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
* Fork the project
* Start a feature/bugfix branch
* Commit and push until you are happy with your contribution
* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
* Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
