Has anyone used this search engine? I used it a few years ago and just recently reinstalled it.
PCWorld has this to say about Google vs Copernic:
A Head-to-Head Comparison
So how good is Google on the desktop? To find out, I took both GDS and Copernic's well-regarded Desktop Search (CDS) tools out for a spin.
GDS downloads and installs in no time. Although I had to free up some space to finish the install (GDS forces you to have 1GB of free space on your C: drive, even if you have another drive installed with ample room, as I did), the application immediately sets out building a central index of your entire electronic existence--but only on the C: drive.
It took a little more than an hour to index about 20G of data--not including Adobe PDF files, which the beta version does not index. The indexing takes place in the background, however, so you can continue to work while it does.
When finished, GDS adds a small, colorful icon to your computer's start menu, which launches the software with a double-click. GDS has the look and feel of Google's familiar Internet search engine.
Users will discover that they can go to Google.com on the Internet and find a "desktop" tab waiting for them there as well. This allows users to easily switch between searching the Internet and searching their desktop, or even to integrate the two into a single search of both their PC and the Web.
However, a search produces an uncategorized list of hits ranked by either relevance or date, just as a Google-only search does. As with search engines in general, a highly specific search with GDS will yield on-target results. But if your request is more general, you might have to wade through long lists of Web pages, Word documents, Excel spreadsheets, and instant messaging texts when all you're searching for is an e-mail message.
Copernic Gets It Right
In contrast, CDS offers a user interface that assists you in sorting and finding data. CDS works as fast as you can type, and your results are sorted according to file type and date. Unlike GDS, Copernic's tool can find PDF files, and will automatically detect external hard drives connected to your PC and index them as well.
But one thing that Copernic's free desktop search engine doesn't do is include secure Web pages in its index. And that's a good thing, since secure Web pages (those whose URL starts with "https") include things like online banking statements and e-commerce sites where your credit card information resides.
With Google's tool, unless you indicate otherwise either at installation or later, all such information is included, even though such pages are supposed to be secure and accessible only if you have entered the correct user names and passwords for your protection. GDS does, however, let you easily select the types of files you want indexed via its Preferences page.
GDS doesn't offer much else in the way of features or customization. Users can restrict the program from indexing portions of their hard drive or other sensitive information. For example, the GDS Preferences page allows the user to enter files into a "Don't Search These Items" box. However, the user must understand exactly where that data is stored and how the Windows file structure works.
GDS even indexes and caches hard drive data protected with an encryption program like Pretty Good Privacy. How? It's simple: GDS adds all viewed documents and pages to its cache--after you've gone through the security handshakes. (Go to Preference to turn off this capability if you miss it during installation. Note that any secure pages GDS already has in its index remain there, but they are hidden from search results unless you choose to include them once again.) I couldn't find any way to stop GDS from caching PGP files or drives--it's similar to the problem this tool poses with the secure Web pages.
And GDS stores its painfully complete index in one "convenient" location on your hard drive, with no encryption or password protection--a hacker's and worm writer's dream come true.
Copernic, in contrast, enables users to select exactly what they want to index using a simple and familiar graphical dialog box that shows the file-tree structure. And they can restrict indexing to a particular hard drive partition or to specific mail folders within Outlook. Users can also decide to index all contacts in their global Exchange address book, or only personal contacts in Outlook.
Copernic users also enjoy greater control over their searches. For example, they can set the application's advanced Preferences so that it skips photo files that are smaller than 16 by 16 pixels, or music files that are less than 10 seconds long. And if extremely large files are a concern, users can manually set (in General Preferences) a size limit for files to be indexed. Those files will always be excluded from searches.
Desktop search is a wonderful concept. Using either of these products can save you time. However, Copernic's tool offers certain protections, thanks to the way its software is structured. With Google's tool, you might do better to wait until its security flaws are addressed.
Copernic is how I found out that a porn site had an essay of mine illegally posted on their website. I had to "prove" the essay was mine. I offered to send them the original with my prof notes scribbled on it. They backed down and asked me if they could have permission to keep it posted.
I like that it keeps the history of what I have searched so I can get a link back a year from now and grab it immediately without having to search again. I can also update a search to see if new links have been added. It will search 17 web search engines at the same time and bring back the top 300 responses.
