beware of solr maxFieldLength option ! It will stop indexing nodes with a lot of attributes

The new solr schema and solr's default value for maxFieldLength (=10000) might skip indexing the attributes of a node when there are to much of them.

To check what's sent to solr, run chef-expander in debug mode.
then use something like this to grep for the data:

grep '<add><doc><field.*</field></doc></add>' /var/log/chef/expander.log

and something like this to roughly count the tokens:

awk '/<add><doc><field.*<\/field><\/doc><\/add>/ {print NF}' /var/log/chef/expander.log

I've been able to trigger the issue on a host with 4096 loop devices (modprobe loop max_loop=4096)
And I've been able to fix it by raising maxFieldLength in the solr config.

As a first step i'd recommend to issue a warning(or error) in expander logs when the number of tokens exceeds solr limits.
