Overview

Note:

It’s possible and common to define just the ‘filter` part of the search definition, for a structured search use case.

A query which allows to combine a query with a filter

Examples:

Find documents about Twitter published last month


search do
  query do
    filtered do
      query do
        multi_match do
          query 'twitter'
          fields [ :title, :abstract, :content ]
        end
      end
      filter do
        range :published_on do
          gte 'now-1M/M'
        end
      end
    end
  end
end
