Re: solrconfig.xml - configuration scope

[Erick Erickson]

What specifically are you seeing? Most things are per-core as you surmised.

There are a few things which, through interaction with Lucene global
variables affect multiple cores, the one that comes to mind is
maxBooleanClauses, where the value in the last core loaded "wins".

There might be some others though, that's the one that I remember.

What version of Solr are you running?

Best,
Erick
