Users of djangosnippets.org may have noticed the addition of a few search-related features over the past several months. I'd like to highlight some of the additions that have been made and show how you can implement similar functionality on your sites. All of djangosnippet's search leans on Apache Solr, a powerful search engine built on top of Apache Lucene (full-text search). Haystack is the search solution for Django apps - it provides a querying interface similar to Django's ORM, handles indexing your models for you, and supports advanced features like "more-like-this" and faceting.

Apache Solr is a fast, open-source search solution. People are doing some very cool things with Solr. I personally have only begun to scratch the surface of what is possible with Solr, but have seen amazing returns with a relatively small investment (thanks entirely to Daniel Lindsley's excellent search framework, django-haystack). There are instructions for getting up and running with Solr + Jetty -- the purpose of this blog entry is to walk through setting up multi-core Solr with Apache Tomcat.
