Or just use the internal document ID: fl=*,[docid]

Granted, the docID may change if a segment merge occurs and earlier 
documents have been deleted, but it may be sufficient for your purposes.

I'm not aware of a simple way.

If you're competent in Java, this could be a neat new DocTransformer
component. You'd say:

fl=*,[position]

and you'd get a new field in your search results.

Cruder ways would be to use XSLT to add it to an XML output, or a
velocity template, but the DocTransformer approach would create
something that could be of ongoing use.
