Subject Zilverline Search Engine version 1.5.0 released
Date Tue, 16 May 2006 20:14:24 GMT

I've just released Zilverline version 1.5.0.

This version adds security and upload functionality, as well as some 
minor fixes and enhancements.

The source will be made available as well very soon.

Zilverline is protected by a Collaborative Source License. You can read
more on this type of licensing at

Zilverline is a fully web based search engine based on lucene that's
ready to roll, and can be simply dropped in a Servlet Engine. It runs
out of the box, and supports PDF, WORD, HTM, TXT, RTF, Excel, Powerpoint
and CHM, and can index zip, rar, and many other formats. Both on
Windows and Linux.

Zilverline supports plugins. You can create your own extractors
for various file formats. I've provided Extractors for RTF, Text, PDF,
Word, Excel, Powerpoint and HTML.

Zilverline supports collections. A collection is a set of files and
directories in a directory. A collection can be indexed, and searched.
The results of the search can be retrieved from local disk or remotely,
if you run a webserver on your machine. Files inside zip, rar and chm
files are extracted, indexed and can be cached. The cache can be mapped
to sit behind your webserver as well.

It's also possible to specify your own handlers for archives. Say you
have a RAR archive, and you have a program on your system that can
extract the content from it, then you can specify that Zilverline should
use this program.

Zilverline indexes in the background, detects ISBN numbers, and has 
(some) IMAP support.

Please take look at, and have a swing at it.
