Why not store a (nonindexed) text field with some internal structure 
(XML, JSON, CSV) that you can analyze after retrieving.  For example,

        ... whatever you want ...

If you use Lux (, which is XML query support on top of Lucene, 
you can do this all automatically, and retrieve the results with a 
simple query like:


plus if you want to pull out the values and manipulate them, you have
