[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-372) ClassBridges are not handled in projection

[Thomas Goetz (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33223#action_33223 ] 

Thomas Goetz commented on HSEARCH-372:
--------------------------------------

Would be very nice, as we do a lot with projection. The current workaround of using a FieldBridge is painfull when used on an IndexEmbedded entity. This slows down index generation dramatically and lets index size grow.

> Values that were stored by a ClassBridge are not accessible via projection. Luke shows the values, so I'm sure they are there. I think Emmanuel is already aware of the problem, as stated here: https://forum.hibernate.org/viewtopic.php?f=9&t=996373&view=previous
> As I run Hibernate Search from within JBoss I'm not quit sure how to demonstrate this bug in a standalone testcase. If someone gave me a hint on how this could be done without too much pain, I'd supply a test case.
> I use the following annotation on the class to be indexed: 
> @ClassBridge(
>         name = "amount_of_students",
>         index = Index.UN_TOKENIZED,
>         store = Store.YES,
>         impl = StudentsSizeBridge.class)
> public class Teacher implements Serializable {
> 	
> 	...
> 	
> }
> As I said, the amount_of_students value is correctly stored in the Lucene index (viewable with Luke), but if I try to project the value within a FullTextQuery it is always empty.
