Ruby writer - arrays for facet data?

[Nigel McNie]

Hi,

I'm using solr to implement a faceted search interface. I found that I
needed the ability to search for *:* so I could get the entire facet
counts, so I upgraded solr from the latest stable to the latest nightly
release.

However, it seems that the ruby writer has changed, or something else
inside solr has changed, because now for the facet data I am getting an
array instead of a hash. Example:

[EMAIL PROTECTED]:~/sounz/solr_server$ curl -s
'http://localhost:8983/solr/select?indent=1&rows=0&q=thea*&facet=true&facet.field=year_group_facet&wt=ruby';
echo
{
 'responseHeader'=>{
  'status'=>0,
  'QTime'=>0,
  'params'=>{
        'wt'=>'ruby',
        'rows'=>'0',
        'facet'=>'true',
        'facet.field'=>'year_group_facet',
        'indent'=>'1',
        'q'=>'thea*'}},
 'response'=>{'numFound'=>5,'start'=>0,'docs'=>[]
 },
 'facet_counts'=>{
  'facet_queries'=>{},
  'facet_fields'=>{
        'year_group_facet'=>[
         '1970-1979',2,
         '1990-1999',2,
         '1980-1989',1,
         '',0,
         '1950-1954',0,
         '1955-1959',0,
         '1960-1964',0,
         '1965-1969',0,
         '2000-2004',0,
         '2005-',0,
         'before-1950',0]}}}

See how the 'year_group_facet' data is in an array instead of a hash, as
it used to be in the stable version.

Is there a reason for this change? From my "hasn't used solr too much
before" perspective, the change does not seem to make much sense.
Perhaps it's a bug?

Thanks in advance anyone who can help :)
