Google Desktop

Google Desktop is desktop search software made by Google for Mac OS X, Linux, and Microsoft Windows. The program allows text searches of a user's e-mails, computer files, music, photos, chats, Web pages viewed, and other "Google Gadgets."

Features

File indexing

After initially installing Google Desktop, the software completes an indexing of all the files in the computer. Oddly, the indexing includes the content of the file, but does not include file names. So if your file is called John Doe, it will not be indexed under Doe if you always refer to him as John in the content of the file.

After the initial indexing is completed, the software continues to index files as needed. Users can start searching for files immediately after installing the program. After performing searches, results can also be returned in an Internet browser on the Google Desktop Home Page much like the results for Google Web searches.

Google Desktop can index several different types of data, including email, web browsing history from Internet Explorer and Mozilla Firefox, office documents in the OpenDocument and Microsoft Office formats, instant messenger transcripts from AOL, Google, MSN, Skype, Tencent QQ, and several multimedia file types. Additional file types can be indexed through the use of plug-ins.^[1] Google Desktop allows the user to control which types of data are indexed by the program.

One unfortunate aspect for users with large hard drives: Google Desktop will only index 100,000 files per drive during the initial indexing period. If you have more than 100,000 files in a particular drive, Google Desktop will not index all of them during this initial period.

Sidebar

A prominent feature of Google Desktop is the Sidebar, which holds several common Gadgets and resides off to one side of the desktop. The Sidebar is available with the Microsoft Windows version of Google Desktop only. The Sidebar comes pre-installed with the following gadgets:

Like the Windows Taskbar, the Google Desktop sidebar can be set to Auto-Hide mode, where it will only appear once the user moves the mouse cursor towards the side where it resides. If not on auto-hide, by default the sidebar will always take up about 1/6 - 1/9 of one's screen (depending on the screen resolution), and other windows are forced to resize. However, the sidebar can be resized to take less space, and you can disable the "always on top" feature in the options. With the auto-hide feature on, the sidebar temporarily overlaps maximized windows.

Another feature that comes with the Sidebar is alerts. When the Sidebar is minimized, new e-mail and news can be displayed on a pop-up window above the Windows Taskbar.

Quick Find

When searching in the sidebar, deskbar or floating deskbar, Google Desktop displays a "Quick Find" window. This window is filled with 6 (by default) of the most relevant results from one's computer. These results update as one types so that one can get to what one wants on one's computer without having to open another browser window.

Deskbars

Deskbars are boxes which enable one to type in a search query directly from one's desktop. Web results will open in a browser window, and selected computer results will be displayed in the "Quick Find" box (see above). A Deskbar can either be a fixed deskbar, which sits in one's Windows Taskbar, or a Floating Deskbar, which one may position anywhere one wants on one's desktop.

Email indexing

Google Desktop includes plugins that allow one to index and search through the contents of local Microsoft Outlook, IBM Lotus Notes, and Mozilla Thunderbird email databases, outside of the client applications' built-in search functions. For Lotus Notes, only local databases are indexed for searching. Google Desktop's email indexing feature is also integrated with Google's web-based email service, Gmail; it can index and search the email messages in one's Gmail account.

Gadgets & plug-ins

Desktop gadgets are interactive mini-applications that can be placed anywhere on the user's desktop – or docked in the Sidebar – to show new email, weather, photos, and personalized news. Google offers a gallery of pre-built gadgets for download on the official website. For developers, Google offers an SDK and an official blog for anyone who wants to write gadgets or plug-ins for Google Desktop. An automated system creates a developer hierarchy called the "Google Desktop Hall of Fame", where programmers can advance based on their gadgets' number and popularity.

The SDK also allows third-party applications to make use of the search facilities provided by Google Desktop Search. For example, the file manager Directory Opus offers integrated Google Desktop Search support.

Release history

Google Desktop was originally developed to bring Google search technology to the desktop. Google Desktop received much attention because it may allow reverse engineering of Google's proprietary search algorithm.

Criticisms

Security

In February 2007, Yair Amit from Watchfire found a series of vulnerabilities^[12] in Google Desktop that could allow a malicious individual to achieve not only remote, persistent access to sensitive data, but in some cases full system control as well. The significant impact and the ease of exploitation forced Google to change some of Google Desktop's logic in Google Desktop version 5.

Privacy

Google Desktop V.3 contains certain features that raise serious security and privacy concerns. Specifically, the share across computers feature that introduces the ability to search content from desktop to desktop greatly increases the risk to users' privacy. If Google Desktop V.3 is set to allow Search Across Computers, files on an indexed computer are copied to Google's servers. The potential for information stored on their computers to be accessed by others if they enable this feature of Google Desktop v. 3 on their computers should be seriously considered. The EFF advises against using this feature.^[13] Also, those who have confidential data on their work or home computers should not enable this feature. There are privacy laws and company policies that could be violated through the installation of this feature, specifically, SB 1386, HIPAA, FERPA, GLBA and Sarbanes-Oxley.^[14]

Other more far reaching concerns arise around the packaging and end user license agreement - specifically the level of intrusion on the local machine and the disclaimers that users implicitly agree to future changes in the license agreement without actually being able to see them immediately.^[15]^[16]

Resource use

Although there have been known problems with the GoogleDesktopCrawl.exe process,^[17] lately the presence of smart indexing has improved the use of resources so this is less of a problem now.^{citation needed} As a default setting, after the user installs the application, files, emails and other data will be indexed at once, in a one-time process. It occurs only when the user's computer is idle for more than 30 seconds and it will usually be complete in several hours. After the one-time indexing, the index is kept up-to-date based on user actions and preferences.

Internationalization/Keyboard

Besides the key combination advertised on the preferences page (hitting Ctrl twice) Google Desktop's Quick Search Box can be launched with a shortcut Alt Gr + g, Alt Gr, however, is the standard key to input diacriticized letters on a QWERTY keyboard, e.g. Ģ/ģ in the Latvian language. Even though it can't be disabled on the preferences page, it can be done through editing the Windows Registry.^[18]
