Text indexing/search with embedded language support

Needing support for text indexes on embedded properties, with language not being enforced at the document level but at the properties itself, like this:

{

  name : "Mitch Pirtle",

  location : [

  {

    "language" : "English",

    "country" : "Italy",

    "city" : "Turin",

    "profile" : "I write code and play bass guitar."

  },

  {

    "language" : "Italian",

    "country" : "Italia",

    "city" : "Torino",

    "profile" : "Scrivo il codice e il basso suonare la chitarra."

  }

}

We already have many apps running like this, as we built a plugin for lithium that uses this approach; and the idea was lifted from a rails plugin that works the same way. I think this is going to become an increasing source of frustration as document schema encourages embedding different languages within the same document.
