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

Hi,

adding a little comment to let you know I finally had the time to have my checkout of solr+lucene
up and ready, and so I am to start having a look inside the code...

I had a few issues building solr in Eclipse, with the XML APIs, has expected there http://wiki.apache.org/solr/HowToContribute#Notes_for_Eclipse_and_the_New_Merged_Lucene.2BAC8-Solr_checkout
, but the workaround wasn't working for me.
(I am running Ubuntu Lucid with Eclipse 3.5.2 and Sun's JVM 1.6, all from apt)

Finally, I was able to build in Eclipse by moving xml-apis jar to the bottom of Build Path,
and this is it.

Maybe updating the wiki could help others...

I'll begin with the "org.apache.solr.search.function" package, and how the DocValues class
is used. I'll probably have a hint of what to do next and ask more questions consequently.

Regards,

> In order to be able to take big advantage of the stats component, it would be great to
be able to define a function as a field.
> Returning the result of a function as a "virtual" field for each document for example,
would enable us to have a much more advanced use of the stats component.
