-------------------------------------------------------------

I'm having an issue with the facet exclude filter parameters (http://wiki.apache.org/solr/SimpleFacetParameters#Tagging_and_excluding_Filters).
I have added this exclude tags and the facet result I'm getting is without collapsing (it's
counting the uncollapsed items).

For example, in my first page it shows something like this (the facet result gives something
like this):

* book (11)
* website (20)
* journal (5)

after clicking on book it shows 11 results correctly, but the faceting with the exclude applied
shows:

* book (230)
* website (25)
* journal (5)

I am using the parameter collapse.facet=after

The collapsed count of books is 11, and the uncollapsed count is 230, I verified it.

> This patch include a new feature called "Field collapsing".
> "Used in order to collapse a group of results with similar value for a given field to
a single entry in the result set. Site collapsing is a special case of this, where all results
for a given web site is collapsed into one or two entries in the result set, typically with
an associated "more documents from this site" link. See also Duplicate detection."
> http://www.fastsearch.com/glossary.aspx?m=48&amid=299
> The implementation add 3 new query parameters (SolrParams):
> "collapse.field" to choose the field used to group results
> "collapse.type" normal (default value) or adjacent
> "collapse.max" to select how many continuous results are allowed before collapsing
> TODO (in progress):
> - More documentation (on source code)
> - Test cases
> Two patches:
> - "field_collapsing.patch" for current development version
> - "field_collapsing_1.1.0.patch" for Solr-1.1.0
> P.S.: Feedback and misspelling correction are welcome ;-)
