I think facet.offset allows facet paging nicely by letting you index into the list of facet values. It is working for me...

One approach would be using facets, but that will just get you the author names (as stored in fields), and not the documents under it. If you really only want to show the author names, facets could work. One issue with facets though is Solr won't tell you the total number of facet values for your query, so it's tricky to provide next/prev paging through them. There is also a 'field collapsing' feature that I think is not in a released Solr, but may be in the Solr repo. I'm not sure it will quite do what you want either though, although it's related and worth a look. http://wiki.apache.org/solr/FieldCollapsing Another vaguely related thing that is also not yet in a released Solr, is a 'join' function. That could possibly be used to do what you want, although it'd be tricky too. https://issues.apache.org/jira/browse/SOLR-2272 Jonathan On 6/1/2011 2:56 PM, beccax wrote: > Apologize if this question has already been raised.
