After having executed a Lucene query, and you access a row in the ResultSet, the bulk loader will prefetch nodes from the DB for the next N rows of the results. There is nothing you need to do to get this - it is built in.

If you want to execute queries directly against the database, you can follow the style of the Hibernate DAO implementations or even the org.alfresco.repo.domain.hibernate.HibernateL1CacheBulkLoader.
