Provides DSL-like macros for search query definition.

Search query definition:

query = search [index: "bear_test"] do
  query do
    nested [path: "comments"] do
      query do
        bool do
          must do
            match "comments.author",  "John"
            match "comments.message", "cool"
          end
        end
      end
    end
  end
end
