trigger delete on nested documents

[Thomas Scheffler]

Hi,

I plan to use nested documents to group some of my fields
<doc>
<field name="id">art0001</field>
<field name="title">My first article</field>
  <doc>
    <field name="id">art0001-foo</field>
    <field name="name">Smith, John</field>
    <field name="role">author</field>
  </doc>
  <doc>
    <field name="id">art0001-bar</field>
    <field name="name">Power, Max</field>
    <field name="role">reviewer</field>
  </doc>
</doc>

This way can ask for any documents that are reviewed by Max Power. 
However to simplify update and deletes I want to ensure that nested 
documents are deleted automatically on update and delete of the parent 
document.
Does anyone had to deal with this problem and found a solution?

regards,

Thomas
