Maybe "Result Grouping/Field Collapsing" might work for you:
http://wiki.apache.org/solr/FieldCollapsing
Otherwise, multivalued string fields, with first and last name combined into
one string might be the best you can do.

Subject: solr nested multivalued fields
I would like to produce the following result in a Solr search result but not
sure it is possible to do? (Using Solr 3.6)
<doc>
<arr name="groups">
<lst>
<str name="firstName">John</str>
<str name="lastName">Darby</str>
</lst>
<lst>
<str name="firstName">Sue</str>
<str name="lastName">Berger</str>
</lst>
</arr>
</doc>
However, i cant seem to manage getting this Tree like structre in my
results. At best I can get something to look like the following which is not
even close:
<doc>
<arr name="groups">
<str>John</str>
<str>Darby</str>
<str>Sue</str>
<str>Berger</str>
</arr>
</doc>
There are two problem here. Firstly, I cannot seem to "group" these people
into a meaningful tag structure as per the top example. Second, I cant for
the life of me get the tags to display an attribute name like "lastName" or
"firstName" when inside an array?
In my project I am pulling this data using a DIH and from the example above
one can see that this is a on-to-many relationship between groups and users.
I really would appreciate it is someone has some suggestions or alternative
thoughts.
Any assistance would be greatly appreciated
