I just released Solr for WordPress 0.2.0. This release completely replaces the default WordPress search without any special setup. I have also added i18n support so people can translate it into different languages, integrated it into the default WordPress theme, and added support to enable or disable specific facets. This release should make it much easier for people to get setup and working correctly. As usual, please let me know of any bugs you might find by opening a report at https://bugs.launchpad.net/solr4wordpress.
I have finally decided to update my site. I have been pretty busy with work the last couple years and have been slacking on the site. Well, I got an itch to start working on it again and decided to kick off my renewed interest with a completely new design. The design is a heavily modified version of the Elixir theme by Michael Whalen.
Along with the new design I have integrated Solr search. Solr is an amazing search engine. I wrote a plugin called Solr for WordPress that handles all the integration between Solr and WordPress. I will be writing a post about the plugin soon.
