Extending Sitecore ContentSearch provider with Solr spell check
During one of our projects we faced with a problem that Sitecore 7 does not support out of the box some cool features of Solr like spell check and similar results , which were in great demand on one of our projects.After some time of investigation with reflector we found out that this kind of customization would not be easy, as a lot of classes in Sitecore provider to Solr wasn't designed to support third party customization. There are a lot of internal classes and important properties hidden in private properties.
