Subject Terminology question: Core vs. Collection vs...
Date Thu, 03 Jan 2013 09:42:02 GMT

I am trying to understand the core Solr terminology. I am looking for
correct rather than loose meaning as I am trying to teach an example that
starts from easy scenario and may scale to multi-core, multi-machine

Here are the terms that seem to be all overlapping and/or crossing over in
my mind a the moment.

1) Index
2) Core
3) Collection
4) Instance
5) Replica (Replica of _what_?)
6) Others?

I tried looking through documentation, but either there is a terminology
drift or I am having trouble understanding the distinctions.

If anybody has a clear picture in their mind, I would appreciate a
