After I compared three popular desktop-search programs a couple of weeks ago, the folks at Google contacted me about a couple of inaccuracies in that post. I had thought that because local files are listed above Web sites when you use Google to search in your browser, the ads that appear on the results page are related to the content of the local files. In fact, Google keeps an index of your local files on its servers only when you enable the Search Across Computers feature, which is off by default. And even then, the index disappears once the search results are delivered. Otherwise the index of your local files resides only on your machine.
The post also stated that Google Desktop Search slows down your PC as it creates and maintains its index of local files. That may be true on Windows XP systems, though the impact is greatest when you install the program and it creates its initial index, but on Vista the search tool uses the OS's own Indexing Service. I use Google Desktop Search on my four-year-old XP machine, and when I uninstalled the program as part of my testing, it appeared to me that the system ran faster, though I didn't perform any precise measurements.
The upshot is that after the initial index, Google Desktop Search affects system performance about the same as any other always-on application (most of which are represented by icons in your system tray). Nor does it pose more or less of a security risk than the other desktop programs you use. (I still prefer Copernic Desktop Search for its easy customization options and clear interface.)
Boost performance by tweaking Vista's indexing options
Just because the Vista version Google's desktop-search tool uses the same indexer as the OS doesn't mean you can't improve its performance by deciding for yourself what file locations it should include in its index. Click Start > Control Panel > System and Maintenance > Indexing Options. Choose Modify > Show All Locations, and uncheck the folders and storage devices you want to exclude. When you're done, click OK to return to the Indexing Options dialog box.

The fastest way to disable Vista's built-in search entirely is to press the Windows key, type services, arrow down to Services, and press Enter. Double-click Windows Search, choose Disabled in the Startup type drop-down menu, click OK, and close the Services window.

You've got your pick of free desktop-search utilities, nearly any of which are faster and less processor-intensive than Windows' built-in file-search feature. I've used at least a half-dozen different file-search tools in the last few years, but three have stood the test of time: Google Desktop Search, Microsoft's Windows Desktop Search (or simply Windows Search in Vista, where it replaces the old Indexing Service), and the oldest and best of the bunch, Copernic Desktop Search. After bouncing between the three, I've settled on Copernic for its speed, ease of use, and relatively small footprint.
That's not to say there's anything wrong with Google Desktop Search or Windows Desktop Search, both of which help you ferret out those important e-mails, Office files, images, videos, and other items you've misplaced on your hard drive and other storage devices (though these locations may not be indexed by default). In my experience both seem to slow things down more than Copernic Desktop Search. Also, Copernic gives you more control over what types of files and other content gets searched, and how often.
Customize Google Desktop Search
By default, this program resets your browser home page to Google, and makes the service your default Web search engine. It also will install a sidebar with news, e-mail, weather, and other gadgets, unless you uncheck this option during its installation. You can change these settings later, if you wish.
Uncheck the default options when installing Google Desktop Search to keep the program from changing your browser settings.
Google Desktop Search indexes all fixed disks on your PC by default. You can add other devices by clicking the down arrow to the right of the search box that the program adds to the taskbar, choosing Options, and selecting Add drive or folder to search in the Search Locations area under the Desktop Search tab in the resulting browser window. This is also where you can enter folders and Web sites you want to exclude from your searches.

A big question with Google Desktop Search is security: If your hard drive is formatted as NTFS, you can choose to encrypt your index and data, but this slows down your file searches and indexing. Google makes its money by serving up ads related to your searches, and that includes those for your local files. Google's privacy statement says the company doesn't make your data accessible without your permission, but the Web search king's track record for privacy is spotty at best.
Tweaking Windows Desktop Search
When it was first released a couple of years ago, I was impressed by Microsoft's desktop-search product, in large part because it was so much faster and more accurate than the file-search options in Windows itself. While it offers more customization options than Google Desktop Search, Windows Desktop Search is slower and clunkier to use than Copernic Desktop Search, though a new version is reportedly in the offing. Windows Search 4 promises to improve searching across networks of PCs and Windows servers, and to support the OpenSearch standard for searching Web services.
You access Windows Desktop Search options by clicking Desktop Search Options on the Options drop-down menu in the top-right corner of the search results window. Click Indexing in the left pane to change the locations the program searches, Advanced to reset the file types it retrieves and place its index file in a different folder, and Deskbar to hide or show the program's search box in the taskbar.
Set Windows Desktop Search to index other locations on your PC via the Indexing Options dialog box.
As the new default local-search service in Vista, Windows Search leaves much to be desired. I've used its Advanced Search options to narrow my searches by file location, date, type, and other attributes, but I'm unimpressed with the results. That's what prompted me to reload Copernic Desktop Search, which I've used on PCs dating back to Windows 98.
The file-search oldster outshines the new challengers
I noticed a difference immediately: Copernic is a breeze to use and customize, and it seems to index faster, while taking a smaller bite out of your system resources. The search-results window is clearer and more intuitive, allowing you to view the results by file type, several of which are shown as tabs along the top of the window. Searching within the results is just as easy and intuitive, and you can search your chosen term on the Web with a single click.
Copernic Desktop Search's results window lets you filter your file searches by type with a single click.
To change your search settings, click Tools > Options, and then select one of the tabs in the left pane to see and reset your options in that category. For example, you use an Explorer-like folder tree to include or exclude locations to be indexed. Adding or removing file types, and changing the folder the index is store in are just as simple.
Change the frequency and idle time before Copernic Desktop Search begins indexing via the Indexing & Performance Settings dialog box.
Copernic Desktop Search shows that there's still plenty of room for specialists in the PC software industry. Maybe there are some programming tricks the big boys haven't figured out yet. I'm thankful for tools such Copernic, which shorten my workday without costing me a penny.
