Acquia, a company that provides open source software for the Drupal CMS, announced the public beta release of its Search tool Wednesday. Those who want to use it can download from Acquia's site and install it as a module on any Drupal 6 site. According to the company, the search will provide navigation, content recommendations, and configurable results weighting. It's built on a redundant hosted service infrastructure, requiring no servers to deploy or manage. The public beta is free and available now with an Acquia Network subscription.
