[clug] searching for a corporate search system

[Andrew]

Hi All,

I am considering purchasing a google mini for a corporate environment 
(searching intranet wiki's, a few other types of web pages, and 
SMB/network shares).  Types of documents that need to be searched (at a 
minimum) would be text, html, pdf, doc. 

Before buying the mini, I thought I should check to see what open source 
systems are available, and I found lots.  To cut through the clutter I 
decided to ask this list... has anyone else here has had a good 
experience with an open source search/indexing system that is fast, easy 
to use and easy to administer? Any pointers are greatly appreciated.



Cheers,
Andrew.
