... but it helps.
I'm prompted to write this post by a throwaway remark from David McCoy, in a post on election statistics: "You don’t have to be smart to search nowadays - all you have to do is enter the key snippet."
Ah, but how do you find the key snippet?
My son had a school essay to write comparing two films, so we thought it would be worth looking on the internet to find some analysis. But if you just search for the names of the films, you just get endless cinema listings and DVD sales, plus a few fairly superficial newspaper cuttings.
So we tried another tack. Who are the key figures (film theory, media studies, sociology) that might be name-dropped in a serious essay? Let's start with Lacan.
When we added "Lacan" to the name of one of the films, the search engine suddenly unearthed an entirely different set of web pages, including a bunch of blogs apparently created as part of a high school project (sixth-form) and talking about a set of related films including the two we were interested in. Could we have found these blogs any other way?
Okay I admit it, my son hasn't read Lacan, hadn't even heard of him, but he had a bit of parental help. The point I'm making here is that sometimes the more knowledge you can put into the search, the more useful the results.
Even Microsoft sometimes misses important stuff when it searches the internet - for example when checking a brand name. See my post on Google and Longhorn.
Internet search looks rather like a P v NP problem. It's fine for checking unoriginality: for example, if the teacher suspects a student of plagiarism, she can put a suspiciously well-phrased sentence into an internet search engine and confirm that the sentence is not original. It is also fine for finding well-structured material: if you want to check Missouri voting statistics, you can probably find something relevant. But if you want to find an unusual thought, you will have to find an unusual combination of search terms.
You do have to be smart to search here.
