I work at a company where we have been doing this sort of stuff for a while now. It's very impressive in the case of Google because of the size of its index and the level of error tolerance of the matching sequence used. I wonder how complete these instant results are compared to the now lame old click-to-submit search results? I tried to test and noticed the count of instant results is slightly smaller but the top items appear to be the same most of the time.
Anyone has insights?
Well speed is nice but I sure don't want to loose quality of search results for that. Google is fast enough as it is. I would say that it's probably unfeasible to process a query over the full web index so there some amount of corner cutting going on here. What type?
