And this Scala
case class to hold the documents retrieved from the view.
It’s a common scenario to retrieve multiple documents at once and the Java driver has a pretty straight forward api for that. The desired keys are simply specified as a json array.

The Java driver deals with strings so it’s up to the client application to handle the json parsing. That was an excellent design decision and makes using the Java driver from Scala pretty painless. I’m using the Play Framework json libraries and an extension method
_.as[TermOccurrence] defined on
ViewRow to simplify the mapping of the response documents to Scala objects.

In order for this extension method to work, it requires an implicit
Format[TermOccurrence] which is defined on of the
TermOccurrence compainion object.
