I think the problem is the desire for the idempotent search results across paging calls. Not sure if that explains it any better than the original poster though. :-)
Basically, if the repeated search gets a different documents returned, the offsets become somewhat problematic. Specifically, a page 2 may skip some of the documents if there were some deletions that affected page 1 or repeat documents if there were some additions. I swore there was an article explaining this whole problem and possible solution, but I can't find it now. I did find the pageDoc reference that seems related, but I am not sure if was actually implemented (JIRA is confusing on this one): http://wiki.apache.org/solr/CommonQueryParameters#pageDoc_and_pageScore Regards, Alex.
