We've been at this "enterprise search stuff" since the early 1990s, first as employees of other companies, and then as New Idea Engineering. This is great for our clients, but recently we goofed. We assumed we meant the same thing that they did when using a particular piece of industry jargon, "Federated Search".
To see a new car model or maybe find a great recipe, all you need to do is enter search words into a public search engine like Google, and something useful will come back in no time. But what if you are a serious researcher faced with issues like developing and launching new drugs or selecting the location to drill an oil well? Millions of dollars are riding on the decision, and you need confidence that your search as has been thorough. You can ask Google and get millions of items in a fraction of a second. But are you willing to rely on a first page result, or look at millions other results to be sure? Serving stakeholders interests and your own career are at stake.
