Just keep one extra facet value hidden; ie request one more than you
need to show the current page. If you get it, there are more (show the
next button), otherwise there aren't. You can't page arbitrarily deep
like this, but you can have a next button reliably enabled or disabled.

Yes that is exactly the issue... we're thinking just maybe always have a
next button and if you go too far you just get zero results. User gets
what the user asks for, and so user could simply back up if desired to
where the facet still has values. Could also detect an empty facet
results on the front end. You can also only expand one facet only to
allow paging only the facet pane and not the whole page using an ajax
call.

How do you know whether to provide a 'next' button, or whether you are
the end of your facet list?

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

There's no great way to do that.
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.

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.

Apologize if this question has already been raised. I tried
searching
but
couldn't find the relevant posts.
We've indexed a bunch of documents by different authors. Then for
search
results, we'd like to show the authors that have 1 or more documents
matching the search keywords.
The problem is right now our solr search method first paginates
results to
100 documents per page, then we take the results and group by
authors.
This
results in different number of authors per page. (Some authors may
only
have one matching document and others 5 or 10.)
How do we change it to somehow show the same number of authors (say
25) per
page?
I mean alternatively we could just show all the documents themselves
ordered
by author, but it's not the user experience we're looking for.
Thanks so much. And please let me know if you need more details not
provided here.
