Hi Marc,
I'm not sure if I follow you completely, but the example you gave is
not complete. I'm missing a few tags in your example. Lets assume the
following response that the latest patches produce.
<lst name="collapse_counts">
<str name="field">cat</str>
<lst name="results">
<lst name="009">
<str name="fieldValue">hard</str>
<int name="collapseCount">1</int>
<result name="collapsedDocs" numFound="1" start="0">
<doc>
<long name="id">008</long>
<str name="content">aaa aaa</str>
<str name="col">ccc</str>
</doc>
</result>
</lst>
...
</lst>
</lst>
The result list contains collapse groups. The name of the child
elements are the collapse head ids. Everything that falls under the
collapse head belongs to that collapse group and thus adding document
head id to the field value is unnecessary. In the above example
document with id 009 is the document head of document with id 008.
Document with id 009 should be displayed in the search result.
>From what you have said, it seems that you properly configured the patch.

>>> 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 ;-)
