Web and desktop search have come a long way over the past ten years, with the likes of Google, Microsoft and Yahoo acknowledging that PC users now expect relevant results in an instant. But while traditional search engines have made great progress in providing an ever-growing number of web pages related to the search terms you enter, the way in which those results are presented hasn't moved forward at all. You're bombarded by pages and pages of lists and, if anything, the results have become too extensive.

Invu hopes to change that with a new search application called Ergo. Unlike the scattergun approach of Google, Ergo groups search results based on relevance – instead of delivering thousands if not millions of potentially useful answers, it provides clusters of results allowing you to instantly dig deeper based on your precise area of interest.

For example, if you search for 'laptops' on the web, rather than pointing you to thousands of sites, it will provide a smaller number of categories such as 'laptop reviews', 'laptop manufacturers' and 'laptop retailers'. And as Ergo is a desktop search tool too, the same principle applies to files stored on your hard disk.

As well as the innovative clustering technique, Ergo uses the cleverness of Microsoft's Windows Presentation Foundation to deliver results in a visually attractive and intuitive way. So, if you're a Vista user, check out our exclusive review of Ergo, and then click on the link at the bottom to try it out for yourself. A beta 2 version is due for release on Invu's YourErgo website on Wednesday 19th December, and Invu plans to launch release candidate 1 at the end of January.

As you'll see from our review, we were impressed by this creative approach to search, and it's certainly an interesting use of the graphical capabilities of Vista. But is intelligent search worth £30? Give it a go, and let us know your thoughts.
