Customising your Desktop Search deployment..
I use this all the time - and use the most basic of features to find what I'm looking for - but now I've found the Desktop Search Administrators guide on Technet. Fantastic! This now allows you to customise how you deploy Desktop search to your organisation and control via group policy which files are indexed.
Here's a tip though. When you deploy Desktop Search - be sure to include this list of query syntax and resources to get the best out of your searches.Print this page out and give it to each user - then they'll make Desktop Search fly...
