I know there are various threads about desktop search applications here on DC, but I want to not be tied down to just one computer. I want to find an open source application that will spider my entire LAN (mostly via SMB, but also HTTP and FTP if possible) and index every file. I want it to grab meta data and use plugins to index the contents of every file. I want thumbnails of image files. I want it to go into compressed archives. I want want to search it all via a web frontend. I want to be able to click on the search results and have either my preferred web browser, FTP client, or (Windows) file manager open to the file.
The first place I am going to look is to see if Google has something like this that is free/opensource. I have found many of the bits and pieces for such an application at the Apache Software Foundation, but it would all need to be glued together.
[update] I just found IBM OmniFind Yahoo! Edition
. It looks like it just might do what I want. I am reading through the website right now.
[update 2] Microsoft has countered this with Search Server 2008 Express
