I want a search engine that tries to find me what I want, as opposed to inundating me with thousands of products for sale, that might remotely resemble something I said.

Here is an example. I am looking for an outdoor security camera. So it needs to be weatherproof. It needs to provide at least 1024 (preferably 1200) horizontal lines. It must have a 100+ Mbit Ethernet connection for data transport and it would be nice to support POE (Power Over Ethernet), but in any event needs to run continuously -- so no battery-powered cams. I don't care either way about pan / tilt / zoom, but might use hardware motion detection.

Try asking your favorite search engine and see the plethora of useless results thrown your way. Lenses. Weatherproof housings. Tons and tons of indoor cameras with 480 lines of resolution. But nothing that meets my needs, regardless of how I phrase my search query.

Maybe what I really want is a search engine that I can interact with and say "I don't like this result because ..." and have the engine filter out all similar results. Google squared is such an approach but it doesn't work, at least for this task.
