- GroupIterator
- This iterator is used to group together documents or document parts which share the same url. For instance, a link document item and the document that it links to will both be stored in the IndexArchiveBundle by the QueueServer. This iterator would combine both these items into a single document result with a sum of their score, and a summary, if returned, containing text from both sources. The iterator's purpose is vaguely analogous to a SQL GROUP BY clause
