The results appear as a Google page, including e-mail results. As a slick bonus, entries for Web pages found in the cache also have a thumbnail image of the Web page itself. The results for Outlook e-mail searches are also slick, although not as convenient as some alternatives. I use a different product for Outlook called Lookout by Lookout Software, recently acquired by Microsoft. Lookout works reasonably well, but is Outlook-only. On the other hand, the search facility works within Outlook using Outlook facilities. So, the results list is a sortable list of messages; you can sort on the folder, date, etc. GDS results are a Google-style browser list.Dont get me wrong, GDS looks like it does everything it could do from a browser, more than youd think possible. When you view a message, it includes links to view it in Outlook, reply or reply to all. Most of these links take you right into context in Outlook itself. I presume it works similarly in Outlook Express, but I didnt test that. I use Outlook 2003. GDS lacks some other features that Id expect as Google refines it, such as the ability to search within the result set. The sorting facilities arent as slick as Lookouts (or some other products), but there is the ability to sort results by date as opposed to the default "relevance" (as determined by Google),and you can view just files or e-mails or Web history or chats. So, GDS isnt quite as powerful on second glance as it is on first. Next page: Privacy and mixed search results.
