  Tutorial: Using Lucene With OJB

Brian McCallister looks at the Lucene search engine and shows us how to index and retrieve objects from a sample Student application.

Tutorial Details:

The Student objects are persisted using ObjectRelationalBridge (OJB); Brian shows us how to query against
the Student index, pull out all the pk's for the hits, then select for the domain objects using those pks.

The primary use case for this application is for a student coop employee to be finding a student in the system, then finding gear and checking the gear out for the student. Finding the student is key, and that is best served by... searching! So we have a database record for each student, and want to have a convenient search facility, which can search based on name, student id (idNumber), phone number, even address. Lucene makes this is a snap. To do it, we just store the id (internal/pk id) in an unindexed field when we add a student in the StudentIndexer:
