Delete relationship without deleted the targeted node using Spring Data Neo4j

Hi,

I've a PostNode with a relation to a PersNode.
I have an assigned ID for PostNode and for PersNode.

The relation between the two is a RelationProperties, with a score (coming from a NER algorithm).

I've successfully added PostNodes, PersNodes and relationships.

But sometimes, I need to delete the RelationProperties between a PostNode and a PersNode without deleted the PersNode (use in anothers PostNode relations).

When I remove the PersNode from the PostNode.pers collections, nothing append, only new and updated relations are propagated.

Is there a way, like in Spring Data JPA, to remove relations when removing from the collection ?
