Blacklight Search (deep dive):

I want to derive a mental picture of a blacklight search. I know that I submit a form and that a query is made against a solr db, the result of which is processed and returnd to me. However, I need a more detailed picture of the interim steps.

Specically I want to get at:

1. What is the function that first receives the forms input?

SSH Tunneling A Multiple Node Span With MacOsX

I needed to get some work done on a jenkins server that unfortunately was behind a firewall, and was inaccessible even with my VPN turned on.

Fortunately I had SSH access to a machine inside the firewall that also had SSH access to the jenkins server. So I knew that there was a way to use SSH tunnelling to get to the jenkins server.

Tunnel between the localhost and the first node.

Enabling Solr Document Versioning

1. What is it?
   • Optimistic concurrency / Document centric versioning constraints
   • Solr rejects older documents with a 409 error.
2. Why?
   • If you are ingesting multiple versions of a document but you don't have a guarantee of the order in which they will be ingested.
3. How?
   • Simply add some configuration to your solrconfig.xml
