I just saw where some software company won a lawsuit of $240+ million against Amazon for patent infringement. Turns out that Amazon unknowingly created their own search functions that were too close to the patented one (the software company agreed that Amazon didn’t steal or copy anything).
ANYWAY, the quote by Amazon went something like “This software allows us to do a very specific search and will find that specific piece of information that relates only to that search.” I guess instead of getting back 100,000 responses that might fit, they get back 10 or something that is quicker to find exactly what one is looking for.
I doubt that Amazon needs that, along with their dozens (hundreds?) of server farms just to sell and ship stuff.
I’m constantly getting ‘suggestions’ related to things I’ve searched for or even bought. Sometimes I want something I don’t even know the name for, and try lots of different possible names. The thing I want always pops up. That could be very useful for Amazon. They’re in business to sell me stuff I want - or don’t want :-)
