Class | Ferret::Search::Sort
In: | ext/r_search.c
Parent: | Object

## Summary

A Sort object is used to combine and apply a list of SortFields. The SortFields are applied in the order they are added to the SortObject.

## Example

Here is how you would create a Sort object that sorts first by rating and then by title;

      sf_rating = SortField.new(:rating, :type => :float, :reverse => true)
      sf_title = SortField.new(:title, :type => :string)
      sort = Sort.new([sf_rating, sf_title])

Remember that the :type parameter for SortField is set to :auto be default be I strongly recommend you specify a :type value.

### Public Class methods

Sort.new(sort_fields = [SortField::SCORE, SortField::DOC_ID], reverse = false) → Sort
