There used to be a project in the UK called WSE (Web Search Environments) which was used to enhance
record search in academic searches. it used to be found at wse.search.ac.uk but the page has been
removed. you can still find some note at http://wse.search.ac.uk/demo.html.
the basic point was to spider a finite number of links down after the main page and index them
slightly differently so you could tell whether it was from the original site or a link further down.
ILRT in bristol I think was leading this project, you could always get in touch with them.
adding this capability to swish-e would be an very interesting feature, I have to say, provided you
can limit the number of level down which the crawler can go. If I remember the report correctly,
they found that the relevancy dropped rather drastically after 2 hoops.
Hope this helps
