Google Delves into the Desktop
Google Delves into the Desktop
Google Inc. upped the ante Thursday in the growing desktop search battle, introducing an application that combines Web results with those from a users hard drive.
In its beta release, Google Desktop Search supports only the most common file formats and applications. But Google plans in future releases to open access to application developers through an API, company officials told eWEEK.com.
Like desktop-search clients, Googles application indexes and searches a users hard drive for Microsoft Outlook and Outlook Express e-mails and files in Microsoft Word, PowerPoint Excel and text formats.
But it also draws results from Internet Explorers history of visited Web sites as well as from AOL Instant Messenger sessions, the company announced.
What stands out about Googles approach, analysts said, is that the search company has merged a users local results with Web results all within Googles well-known Web-site interface. When they conduct a combined search, users are taken to Googles site, where desktop results appear in a highlighted area above the typical Web results.
Users can choose to search only their desktops, which appear in a local Web page. But in its own testing, the Mountain View, Calif., company found that users care less about where information is stored and more about being able to find it, said Marissa Mayer, Googles director of consumer Web products.
"Users no longer understand the difference between their hard drive and the Web," Mayer said in a discussion with eWEEK.com. "All they can remember is that theyve seen something."
For the beta launch, Google focused on file formats from applications with the highest market share, which explains the support for Microsoft files and AOLs IM, Mayer said.
Google Desktop does not search for common Web data exchange formats such as Adobe Systems Inc.s PDF (Portable Document Format), nor does it retrieve Web history information from alternative browsers such as Mozilla Firefox.
Google, though, is working on expanding support for other formats. Already, it is considering adding PDFs, Lotus Notes e-mail and other IM services, Mayer said.
More telling, it also expects to create an API so that application developers themselves can create plug-ins for Google Desktop and make their files searchable. Mayer did not know when that would occur.
"Its important that we get comprehensive," Mayer said. "Were still thinking about details of [the API], but there are thousands and tens of thousands of applications, and users want to do a comprehensive search across them."

More Desktop Search
Googles launch comes amid growing interest in desktop search among major Web search engines and companies. This week, details began leaking about AOLs intentions to include desktop search technology in its forthcoming AOL Browser.
Ask Jeeves Inc. also bought a desktop-search company and is working on a product for this year.
A slew of vendors focus more exclusively on desktop search, such as X1 Technologies Inc., Copernic Technologies Inc. and ISYS Search Software Inc., and many were quick to point out Thursday that their applications index a broader array of files and provide greater functionality to refine results.
To Gary Stein, a senior analyst at Darien, Conn.-based Jupiter Research, Googles beta release has raised the bar for its search competitors. He was particularly struck by the way Web and desktop results are integrated together and the speed with which the desktop application indexes files.
"Theyre calling it a desktop application, but its really not," Stein said "This is a fairly major leap [because] its really the integration of local and network data resources all under one interface."
Mayer said about a dozen Google researcher and engineers, led by senior researcher Steve Lawrence, worked over the past year to create Google Desktop. The application is a 400 KB download and typically can index a users hard drive within five to six hours.
It then conducts real-time indexing and includes technology to adjust indexing as a user performs processing-intensive functions to avoid interfering with other work, Mayer said.
One technical hurdle it has yet to overcome is being able to include e-mail messages from Googles Gmail service in the index.
Google is working to fix the incompatibility in the desktop search products next release, Mayer said.
As far as privacy, Googles desktop application lets users choose which information to include in the index, and they can later delete specific files, e-mails, chats and Web sites from searches, Mayer said.
Google Desktop Search is available as a free download for Windows XP and Windows 2000 Service Pack 3.
