i'm a newb: questions about schema.xml
Hello,
I'm a Solr newb. I've been poking around for several days on my own test instance, and also online at the info available. But one thing just isn't jiving and I can't put my finger on why. I've searched many many times but I don't see what I'm looking for, so I'm thinking perhaps I have a fundamental semantic misunderstanding of something somewhere. Everywhere I read, everyone talks about schema.xml and how important is. I fully get what it's for but I don't get where it is, how it's used (by me), how I edit it, and how I create new indexes once I've edited it.
I've installed, and am successfully running, solr 5.0.0 on Linux. I've followed the widely recommended-by-all quick start at: http://lucene.apache.org/solr/quickstart.html. I get through it fine, I post a bunch of stuff, I use the web UI to query for, and see, data I would expect to see. Should I now have a schema.xml file somewhere that is somehow connected to my new index? If so, where is it? Was it present from install or did it get created when I made my first core (bin/solr create -c ati_docs)?
[root@machine solr-5.0.0]# find -name schema.xml
./example/example-DIH/solr/tika/conf/schema.xml
./example/example-DIH/solr/rss/conf/schema.xml
./example/example-DIH/solr/solr/conf/schema.xml
./example/example-DIH/solr/db/conf/schema.xml
./example/example-DIH/solr/mail/conf/schema.xml
./server/solr/configsets/basic_configs/conf/schema.xml
./server/solr/configsets/sample_techproducts_configs/conf/schema.xml
[root@machine solr-5.0.0]#
Is it the one in /configsets/basic_configs/conf? Is that the "default" one?
If I want to 'modify' schema.xml to do some different indexing/analyzing, how do I start? Make a copy of that schema.xml, move it somewhere else and modify it? If so, how do I create a new index using this schema.xml?
Or am I running in "schemaless" mode? I don't think I am because it appears that I would have to specifically state this as a command line parameter, i.e. bin/solr start -e schemaless
What fundamentals am I missing? I'm coming to Solr from Elasticsearch, and I've already recognized some differences. Is my ES background clouding my grasp of Solr fundamentals?
Thanks for any help.

Re: i'm a newb: questions about schema.xml
Posted by Erick Erickson <er...@gmail.com>.
This is key: managed-schema
You've managed to get things started with the "managed schema".
Therefore, you need to use the REST API to
add/subtract/multiply/divide. This is different than "schemaless",
although it _is_ related. And they're both different than having a
schema.xml to edit.
Or start over _without_ a managed schema, not quite sure how you
started that way in the first place ;). You may have used bin/solr
start -e schemaless.... when you started and maybe forgot?
Here's a place to start:
https://cwiki.apache.org/confluence/display/solr/Managed+Schema+Definition+in+SolrConfig
Best,
Erick

Hi Shawn,
Definitely helpful to know about the instance and files stuff in Admin. I'm not running cloud, so I looked in the /conf directory but there's no schema.xml:
Here's what's in my core's Files:
currency.xml
elevate.xml
lang
params.json
protwords.txt
solrconfig.xml
stopwords.txt
synonyms.txt
and echoed by ls -l:
-rw-r--r-- 1 root root 3974 Feb 15 11:38 currency.xml
-rw-r--r-- 1 root root 1348 Feb 15 11:38 elevate.xml
drwxr-xr-x 2 root root 4096 Mar 23 10:46 lang
-rw-r--r-- 1 root root 29733 Mar 23 18:04 managed-schema

Hopefully you know what core you are using, so you can go to the admin UI and find it in the "Core Selector" dropdown list. Assuming you can do that, you will find yourself looking at the "Overview" tab for that core.
https://cwiki.apache.org/confluence/display/solr/Using+the+Solr+Administration+User+Interface
Once you are looking at the core overview, in the upper right corner of your browser window is a section called "Instance" ... which has an entry that is ALSO called "Instance." Inside the directory indicated by that field, you should have a conf directory. The config and schema for that index are found in that conf directory.
If you're running SolrCloud, then you can forget everything I just said ... the active configs will be found within the zookeeper database, and you can use the Cloud->Tree tab in the admin UI to find your collections and see which configName is linked to each one. You'll want to become familiar with the zkcli script in server/scripts/cloud-scripts.
https://cwiki.apache.org/confluence/display/solr/Command+Line+Utilities
Whether it is SolrCloud or not, you can always LOOK at your configs right in the admin UI -- click on the "Files" tab after you select the core from the selector.

Shawn

Yes, this is the correct page which will tell you more about this
"managed-schema" thing in Solr 5.0.0. I got stuck in this for quite a while
previously too.

Pretty sure I found what I am looking for: https://cwiki.apache.org/confluence/display/solr/Managed+Schema+Definition+in+SolrConfig
I noticed the "managed-schema" file and a couple Google searches with that finally landed me at that link.
Interesting that the file is hidden from the Files list in the Admin UI.

Hopefully you know what core you are using, so you can go to the admin
UI and find it in the "Core Selector" dropdown list. Assuming you can
do that, you will find yourself looking at the "Overview" tab for that core.
https://cwiki.apache.org/confluence/display/solr/Using+the+Solr+Administration+User+Interface
Once you are looking at the core overview, in the upper right corner of
your browser window is a section called "Instance" ... which has an
entry that is ALSO called "Instance." Inside the directory indicated by
that field, you should have a conf directory. The config and schema for
that index are found in that conf directory.
If you're running SolrCloud, then you can forget everything I just said
... the active configs will be found within the zookeeper database, and
you can use the Cloud->Tree tab in the admin UI to find your collections
and see which configName is linked to each one. You'll want to become
familiar with the zkcli script in server/scripts/cloud-scripts.

Whether it is SolrCloud or not, you can always LOOK at your configs
right in the admin UI -- click on the "Files" tab after you select the
core from the selector.
Thanks,
