Overview

Custom Filters Score

Author: Jerry Luk jerryluk@gmail.com

Adds support for "custom_filters_score" queries in Tire DSL.

It hooks into the Query class and inserts the custom_filters_score query types.

Usage:

Require the component:

require 'tire/queries/custom_filters_score'

Example:

Tire.search 'articles' do
  query do
    custom_filters_score do
      query { term :title, 'Harry Potter' }
      filter do
        filter :match_all
        boost 1.1
      end
      filter do
        filter :term, :author => 'Rowling',
        script '2.0'
      end
      score_mode 'total'
    end
  end
end
