Is there a general summary page of Solr best practices? And particularly one for sizing Solr nodes, shards, and collections?
We do not have general advice for hardware sizing. There are many things involved in coming up with a recommendation. And we often find that if we do make a recommendation without asking a ton of questions that people often cannot answer, it ends up being the wrong recommendation. It's sometimes the wrong recommendation even if we DO ask a ton of questions and receive answers.
One rule of thumb that I find is almost always true: It's probably going to require more memory than you think it will.
I run a Solr server that provides full-text search for my dovecot install. The index is about 600 megabytes, with about 150K documents. This instance runs successfully with a 256MB heap, even when doing full index rebuilds. I didn't think I could run it with such a small heap, because usually people need to increase the default heap size of 512MB.
