Can Related Content be accessed via the API?

(from github.com/jdeathe)
Is it possible to access the new Related Content value from the GSA and/or JSON API response or in the Site Search results? I can only get it to output on the Fess search front-end.

The use case is for an alternative to the “promotions” feature.

I’ll add it to JSON API in next release…
