Are questions related to configuring Apache Solr on topic at DBA? By sheer number of questions, I'm uncertain. DBA has 1 question tagged for solr, Server Fault has ~150, and Stack Overflow has ~11,000.
While preparing for a production environment, I've had a few questions related to Apache Solr which I eventually figured out the answers to but they were not readily available or apparent through searching:
What characters are valid for a core name? (equivalent to an SQL table).
The answer to this is pretty simple, but it's undocumented.
How do you share the core configuration between multiple cores? (equivalent to sharing a table definition between identical table structures, but with different data sets in SQL).
This has been answered twice on Stack Overflow about specific older versions, but for newer versions there is a built-in feature.
Would these questions be appropriate here?
