Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiMjVjZWVk... ) / Improvement ( https://hibernate.atlassian.net/browse/HSEARCH-4895?atlOrigin=eyJpIjoiMjV... ) HSEARCH-4895 ( https://hibernate.atlassian.net/browse/HSEARCH-4895?atlOrigin=eyJpIjoiMjV... ) `.id()` projection / `@IdProjection` within object fields ( https://hibernate.atlassian.net/browse/HSEARCH-4895?atlOrigin=eyJpIjoiMjV... ) Change By: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Currently this mapping will fail: {noformat}public record BookProjection BookDTO (@IdProjection id, @ObjectProjection AuthorDTO author) {}; public record BookProjection AuthorDTO (@IdProjection id, @FieldProjection name) {};{noformat} … because the {{@IdProjection}} is not allowed within an object projection. That makes sense, because {{@IdProjection}} is about the root document ID. But it’s not very intuitive. Maybe we could extend the ID projection to allow referring to object IDs as well?
