What is the best way to hire Solr developers?
My answer to What is the best way to hire Solr developers? on Quora
Do you really need to hire a Solr specialist? It shouldn’t take a competent developer more than a few days to get familiar with Solr—the HTTP API is extremely easy to work with in my experience. You can always hire in a consultant from one of the companies that provide commercial Solr support for a few days to help your developers get up to scratch.
