Subject Re: [POLL] How do you (like to) do logging with Solr
Date Tue, 17 May 2011 13:01:45 GMT
I'm not a Solr/Lucene programmer.  I'm a guy who does web sites (using
PHP!) who wants a good search engine.  And the search *functionality*
in Solr rocks - great job, guys!

Considering that, I don't really care how Solr logs things.  I just
want it to be straightforward and well-documented.  Which it currently
is not.

Just my personal perspective.
