Uwe Schindler commented on SOLR-6016:
-------------------------------------
This is just one reason why I completely disagree with schemaless mode. It was
really a stupid idea to have this in Elasticsearch and now - just because ES
has it - Solr must somehow copy this horrible default behaviour. Sorry, this is
all a very negative experience to everybody trying to use Solr.
In my opinion, it is much better to enforce people to define their schema
before using Solr, although its more work. But fixing your schema/mapping once
it was created is a bigger headache. Because you have to look at your data in
any case.
