  <P><B>This help suck.  I can't put it in words - mind to help?</B></P>
  <P>Drupal provides a tool to tackle to manage this complex relationships between different pieces of content.  This module allows you to create a hierarchy of flat and nested containers for organising and navigating through content.  Drupal's indexing system can also be used to provide indexing outside of the underlying repository.  It enables indexing of contents where the underlying repository itself does not (meaningful relationships across your hierarchy) by using sets of keywords and meta-data.</P>
  <P>Each entry you add can be given a <I>collection</I> which indicates the group or meta-type <I>entries</I> belongs to.  For example, if you have a website about traveling, the index for the collection "Destination" may contain the entries or values "France", "Italy", "England" and so on.  The "entries" page lets you view all entries along with the collection and keywords they associated with.</P>
