Advanced DNN search engine module
The psSiteSearch search engine module is a direct replacement for the built-in DNN search module.
Based on Lucene.net, it includes a web spider which will crawl your site and gather all page URLs, enabling you to have a real search engine on your own website!
Using psSiteSearch will give you much more control over your website search results and will provide your users with more accurate results.
The search engine will honour your robots.txt file and also any page META directives including "no index" and "no follow".
