Neo4j wraps Lucene in a thin layer which makes it transactional. It's fully ACID and can participate in the same transactions as neo4j operations. It's modeled as its own data source in an XA environment (the neo4j graph is another XA data source) with a logical log for commands so that it's safe for crashes and will participate in the recovery process just like any other XA data source, f.ex. the neo4j graph.
