Thanks for using the word bewildering, I agree.
While we are talking of simplifying solrconfig.xml, may I mention YAML?
I find the YAML format so much more readable than XML.
I have not looked at the code which reads the config, so I do not know
how big a change it is to use cfg4j and read in YAML.
Perhaps I should ask this on the dev list. And I hope I am not
revisiting a discussion which has already been decided.

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

I’ve done solid good practice (Zookeeper ensemble, chroot, data on EBS

but I’m stuck with a completely non-instructive stack trace.
We run a separate data directory and SOLR_HOME, which is poorly supported
by
the startup script. I gave up and used a symlink to make it sorta happy.
Still, I’m stuck with this.

I’ve tried loading configs with bin/solr and with zkcli.sh. I get useless
error messages
from each of them.
I worked on a commercial search product for ten years, and this wouldn’t
pass basic QA.
We need to do some work, people.
Last week I had to upgrade a proof-of-concept demo that ran on Solr 4 to
6.2.1, using the Sunburnt client. I thought I'd use the Files example to get
started. This wasn't exactly painless: I ended up having to disable Managed
Schemas (I couldn't get Solr to use the old schema.xml), mess around with
Sunburnt (which assumed a certain URL structure to read schema.xml) and
generally chop large chunks out solrconfig.xml until it began to work.
When we see clients with Solr issues the problems often stem from there
being *too much* in their configuration - they've started with one of the
example configs and added often conflicting settings, there's all kinds of
irrelevant stuff hanging around (you probably don't need a Hungarian stemmer
unless you're Hungarian), a zillion schema types you'll never need...I'm
beginning to wonder if an absolutely minimal Solr example configuration
might be a good idea. It's going to have to make assumptions (e.g. it's
probably going to assume English content) and it won't do anything
particularly clever, but I feel it might be a better place to start than
wondering what on earth all that commented-out XML does, especially the bits
that say 'you probably shouldn't use this in production'. You can always
copy those bits back in later...
I'll be in Boston next week if anyone wants to chat about this. Maybe I'll
have a go at our Lucene Hackday on Tuesday (still some places free!)

Hello,
Three weeks ago I asked this list whether there was an interest in
running a virtual examples reading group, with "all questions
welcome". The response was sufficient to start planning the first
study group.
The current projected date is start of November. You can register for
it at: https://www.surveymonkey.com/r/YLNVC27 (it is the same survey
as the first time - no need to do that again if you responded before).
The first run is free.
Regards,
Alex.
P.s. If you have Solr-using customers (e.g. you are running a Solr
cloud business), feel free to announce this to them and/or run your
own outreach and contact me directly with bulk emails of those
interested.
P.p.s. I am also presenting on Solr examples at the Lucene/Solr
Revolution in about a week. If you have very strong opinions about
Solr examples, feel free to reach out directly and share them via
email or in person. The opinions do not have to be positive, though
having them constructive would be an nice. :-)
