I just recently encountered a use case where I needed to perform ranged searches in Drupal against a Solr back-end. This ended up being far easier than I ever anticipated. Here's a quick walkthrough of the steps involved to expose a CCK field to Solr and then explicitly use it when conducting searches. This was done using a Solr 1.4 engine and http://drupal.org/project/apachesolr 6.x-1.0-rc5
This took me a while to figure out and ended up being quite simple once complete ... I hope it saves someone the headache I got from trying to figure it out! So here we go ... in 3 simple steps.
