Getting Results by grouping in solr

hello everybody
i have to return document from solr only for the latest year. LIke for
example i have 3 documents for 2009 honda accord Coupe bodystyle and two for
2008 honda accord coupe bodystyle. i need to get the latest of results for
make,model,bodyStyle. If i give the query 
make:Honda+model:Accord+bodyStyle:Coupe
 i get all the entries i want only max year returned ie only 2009 styles,
hence my end resutl should be only 3 doc. Is there a max function in solr. 
doc>
  <field name="year">2009</year>
  <field name="make">Honda</year>
  <field name="model">Accord</year>
  <field name="bodyStyle">Coupe</year>
  <field name="id">1</1>
</doc>
<doc>
  <field name="year">2009</year>
  <field name="make">Honda</year>
  <field name="model">Accord</year>
  <field name="bodyStyle">Coupe</year>
  <field name="id">2</1>
</doc>

  <field name="make">Honda</year>
  <field name="model">Accord</year>
  <field name="bodyStyle">Coupe</year>

I do not think it is easily possible.

solr has a max function but I do not think it is usable here.

Wrong list.
Use solr-user instead.

Look at SOLR-236.
Check markmail.org.
