Hello, there's a limitation in Hibernate Search's capabilities of mapping structured objects, there's a good explanation of this problem here: https://forum.hibernate.org/viewtopic.php?f=9&t=1001551 This is something I'm aware of since my first use of Search, I was assuming you know about it? I couldn't think of a good solution so far, besides the awful workaround I suggested in the forums. Better ideas? Sanne
