[TYPO3] indexed search not indexing database records

[Antonio Reher]

Hello everybody:
in my site, I hold a bunch of database records in  a page, and I view 
them via a plugin and a get parameter with their ID. In other words, 
using realurl, I have:
Root:
    - documents.html
in documents the records have been inserted via the list module and they 
have been defined in my extension with data such as:
- title
- date
- bodytext
- abstract
etc

then, in documents.html I configure a plugin, tx_geps.pi1, which has two 
parts: a list of the records (if $_GET['n'] is not set) and the details 
of a record (where uid is $_GET['n']).

It all works fine, but my problem is that the indexed search engine 
doesn't seem to index documents.html?n=1, documents.html?n=2, etc.

Am I missing something in the cofiguration of indexed search?

Thanks!

Antonio
