Zilverline Search Engine - Zilverline is what you could call a 'Reverse Search Engine': Zilverline is a search engine that offers web access to your personal or intranet content. Zilverline is a 'Lucene Desktop' comparable to Google Desktop, but based on Lucene. Zilverline supports collections: a set of files and directories in a directory. Zilverline extracts content from PDF, Word, Excel, Powerpoint, RTF, txt, java, CHM as well as zip, rar, and many other archives. A collection can be indexed, and searched. The results of the search can be retrieved from local disk or Intranet. Files inside zip, rar, chm and other archives are extracted during indexing, and can be preserved for searches. Otherwise they are extracted 'on-the-fly'. You can store indexes and caches wherever you like, you could for instance store them on a DVD, as long as Zilverline (and your webserver) can access them. Zilverline is built in Java on top of Lucene and Spring. You need a Servlet Engine, such as Tomcat to run it.
