Sounds like a perfectly good thing to do. The only limitation you'll have (by storing a reference to the project in Lucene rather than the project data itself) is that you won't be able to query both the document text and project metadata at the same time. For example, "documentText:foo OR projectName:bar" . If you have no such requirement, then seems like storing the ID in Lucene which refers to a database row is a fine thing to do.
