Configuring Solr to use UUID as a key

Question

I am trying to configure Solr 4 to work with UUID and so far I am unsuccessful

From reading the documentation I have seen two different ways to configure schema.xml

Answer 1

After some work here is the solution:

In schema.xml, add (or edit) the field field

In solr config, update the chain and add the chain to the handlers (Example: for /update/extract):

  
    id
  
  
`         


  
    true
    ignored_
    true
    links
    ignored_
    uuid
