If you let me know how you use grep to search the internet as effectively as I do with Google, sure!
I can search the internet way better. Email me what you are looking for and 9 times out of 10 I will send you back something better than what Google will spit out. Furthermore you won't even have to sift through 10 links, or change your search, I will do all this and send you the result back.
What are you even proposing, human search agents? That's absurd.
They do. Most companies which build their primary product on some form of heuristics have "domain experts" who help filter the wheat from the chaff.
Ok, so you agree partially.
Can you do it for me in 100ms or better
Not all searches require an immediate reply, so I'll just focus on those. Looking at the list of the most expensive keywords on Google, it is safe to say the vast majority consist of searches that do not necessitate a decision at the moment of the first try. Think Attorney, Insurance, Travel.
and at no cost?
Yes. It is free, and ad supported.
