Google does this to some extent. Recently I've found that Google uses my past queries to make cogent suggestions for my next search (essentially to predict what I want next based on prior info). Eg, if I've just searched for "sully", then a short time after type "t" into Google, the first suggestion is Tom Hanks. I've only noticed this in the last few months.

My favorite example of this is the Bullet physics library.

Google eventually learned to give me documentation in response to stuff like 'bullet collision', but for awhile it was big on youtube links and gun ranges.

I’ve experienced this when learning new programming languages and other domains. When you start, Google results are mostly garbage with a few useful bits. A few months later, it feels like the web is awash in materials to answer your every question and you can always find an answer for your problem in the first 5 results.

Part of it is learning which phrases to use when searching, but I’m sure a big part of it is also Google figuring out what you want.
