Get Lucene document number

Hopefully a simple question. Is it possible to get the Lucene document (number) associated to an entity?

sure, but you need to make a fulltext query. Just search for the entity by primary key, and then use projections to load FullTextQuery.DOCUMENT_ID as in
http://docs.jboss.org/hibernate/search/ ... rojections

Remember that the document id is likely to change when writes happen to the index.

I wonder if this might be useful to do what i'm trying here https://forum.hibernate.org/viewtopic.php?f=9&t=1014909 Is the DOCUMENT_ID the same number used to create the Lucene index files?

No, not related.
