Since I started this thread, more articles about the subject have been published on the internet like these:
Fast is known for being good on enterprise search and Autonomy is regarded as one among many competitors including
Google.
One interesting article:
The Future of Search is Simpler
"In a sharp contrast, Google provided more vision in their 10-minute lunch pitch than Autonomy's same old key note speech. Google provided a clear vision: you can be up and operational in one day and search everything. Simple to use and simple to administer. In 2008, Google is not the naive implementation that we saw 6 years ago: they have made real progress toward their vision. While other companies are marching to that vision. Dieselpoint's OpenPipeline, Endeca's simple administrative controls, Fast's navigators, Autonomy's categorization, Google is providing the vision. The future is simpler and usable by everyone on the enterprise. We have along way to go - but we can change the business world. We are moving closer to the vision of many sources of data providing insight and increasing the pace of business decisions".
