All Documents have a unique document Id that identifies them as "the same" entity, but the boundary docs provide additional evidence that they are the start and finish of a set of documents all related to the same concept by providing a "CodeBoundary" identifier indicating this is the start or end of the document set for this entity representation. This effectively flattens the entity to properties relationship by adding all entity information to each property document which includes up to 34 indexed fields and about 9 stored fields.
Proposed Relational Indexing Implementation under Lucene 5.0.0
...
A query is constructed to provide a wrapper to queries to the children of the parent document returning all matching document contained in the parent. Filters on the parent, such as whether it is active or not work against the entity metadata contained there. A collector verifies and provides sorting support for the result (formerly HitCollector)
