RE: [E] Re: Stemming and Managed Schema
Awesome,
So just to make sure I got it right:
I would edit the managed-schema, make my changes, shutdown solr? And start it back up and verify it is still there?
Or is there another way to reload the core/collection?
Thanks!
Sas

You can't edit an existing fieldType with the Schema API. You can entirely replace it, but you have to include the whole definition.
https://cwiki.apache.org/confluence/display/solr/Schema+API#SchemaAPI-ReplaceaFieldType
I'm aware that the managed-schema file says to not make manual edits -- but you *can* edit it manually, as long as you are absolutely sure that nobody is using the Schema API until after you complete your edits and reload the core/collection.
Thanks,
Shawn

Isn't just reloading the core via Admin interface sufficient?
I though that all Solr driven changes are written out to managed-schema at
once, so as long as core is reloaded right after manual changes, it should
be OK.

Actually, I prefer to do it the other way:
1> shut down Solr
2> edit managed_schema
3> start Solr.
that eliminates any possibility of inadvertently overwriting your
changes by issuing a managed schema call.
that's a nit though, either will work.
FWIW,
Erick

That's the sledgehammer approach. Simple and effective, but Solr does
go offline for a short time.

For SolrCloud:
