The distinct count of the facets is available with Solr 4.0 (as of writing).
The Solr patch SOLR-2242 would aid to provide with the number of facet terms.

Few key things to take into account when using fields for Sorting in Solr –
Documentation –
Sorting can be done on the “score” of the document, or on any multiValued=”false” indexed=”true” field provided that field is either non-tokenized (ie: has no Analyzer) or uses an Analyzer that only produces a single Term (ie: uses the KeywordTokenizer)

<!-- Fields defination --> <br /> <br /> <br /><br /><br /><!-- Copying subject field to subject_text field --> <br /><br /><br /><!-- The subject_text cannot feed into text.So you would land up with no subject being copied --> <br /> <br /> |
The copy is done at the stream source level and no copy feeds into another copy.
So a copyfield cannot be a source of other copyfield tag.
The copyfield source must be an actual field, which has some value and does no cascade.
