I'm using Lucene/Digester etc for my MScs o I'm quite new to these API.
I'm trying to obtain advice but it's hard to say whether the problem is Lucene or Digester

I trying to index the INEX collection but when I try to index repetitive elements only the last one is indexed. For example:

only the last Chapter element will be indexed and it will skip the first two.
Thanks in advance.
