I have a class that extends another class. The base class has the @Id, but I want to search the derived classes (they have the Fields).

When I try to simply start up Spring I get:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [config.xml]: Invocation of init method failed; nested exception is org.hibernate.search.SearchException: No document id in: com.ontometrics.portal.contributions.Post

Read more of the doc and found that it was looking for a different id annotation.
