The more I use it, the more I like Windows Desktop Search, which is included with the MSN Search Toolbar. I especially like that you can use command line operators to create custom search requests, and you can save searches as Internet shortcuts.
I’ve found a few glitches, including one that’s very annoying. I use Outlook Express only as a news reader and not for e-mail; that means the newsgroup files get indexed, and I can search for words, phrases or people just by entering store:oe as one search term.
But here’s the glitch: The resulting list contains a series of posts that include the search term I specified. Some posts are HTML, some are plain text. I can preview the text posts, but the preview pane is blank for the HTML-formatted messages. I’ve searched the FAQ and the newsgroup and find nothing to indicate that this is a known glitch. Outlook files can be previewed regardless of their format.
Anyone from the MSN team reading this and want to comment? Scoble, can you forward this to someone who might be able to help?

I love MSN Desktop Search too, but I’ve had to stop using it because it crashes Outlook. If I run the indexer for more than a couple of minutes, Outlook crashes out with a GPF. I haven’t been able to get in touch with any of the MSN Search guys to get this worked out either — sent feedback from the blog, etc… no luck…
