Subject Re: (ANNOUNCEMENT) Solr Examples reading group

Charlie:

I like that idea. It's bewildering how much stuff is in the config. I
do think there's value in having it all there though since people
won't even know to look in, say, "kitchen-sink-solrconfig.xml" for all
the _other_ things that can be done....

Perhaps comment out all the "extra stuff" and move it to the end of
the config files?

And how many people have been tripped up by un-defining the "text"
field in the schema and still having things break by the "df" field
being set to text in solrconfig.xml?

FWIW,
Erick
