Instance Method Details

#search ⇒ Object

Fetches search hits and paginates them. In case of an error, flashes appropriate error messages.

For use in views, hits are stored in the @hits variable. Pagination is done using the limit option (defaults to 10). You can change that limit by subclassing DefaultSearchController and then overwriting to CustomSearchController.options = {:limit => X}.

To customize the pagination, you should subclass DefaultSearchController:

class SearchController < RailsConnector::DefaultSearchController
  def search
    # What this method should do:
    #  * Initialize a SearchRequest obj
    #  * Paginate the results
    #  * Fill the @hits variable for your views
    #  * Flash on errors
  end
end
