Subject Re: Solr, MultiValues and links...

Hmmm, MultiValues are guaranteed to be returned in the order they were
inserted, so you might be able to do the linking yourself given the results.

But have you considered grouping (aka field collapsing) on the ISBN number?
If you indexed each record uniquely, that might do what you need.
