Epsom Salts And Hair Loss

MacLeod, The unquenchable

on the screen of my computer is it: Google, Great Search. Front to him, staring at him, that's me: a seasoned internautical machine with hundreds or thousands or millions of hours of computer experience, which everyone calls a MH (Very Hacker). I have to look for the story to my nephews. Google searches are no secrets for me, but I'm rather flojillo stories. I know that I'm looking for is titled "Nosecuantos Blancaleches and Dwarfs." I do not remember exactly how many were the bloody gnomes, or how exactly the whore called (pardon me). What would a layman with this data? Look for "dwarfs", which is the only term insurance leads. A's see ...




Dwarfs



Result (check it out!): Too many dwarfs. Well, here I go, the animal computer. Let's try the name, which certainly do better. What do I do when I find on my machine a file whose name begins with "White" I do not know how it ends? Search for "White *"! Yast, since Google will be the same, di-go-yo. So try it ...

White *


Result: Uh, oh, for the little king of computers seems to have fallen upside down ...! turns out that Google does not support "stemming" which what we call the MH to the ability to use a wildcard instead of part of a term in a search. Are we lost? "We have no choice but to dive into the maelstrom of dwarfs that offers the first search?


Tachánnnnn, tachínnnnnn, pi-pi-pi (tune of tension


great crescendo of scary movies)

Noooo, tranquiii ... Google supports asterisks as part of a consultation, but the meaning assigned to them is not part of a word, but of a whole word. That is, if we seek "the * red" get all pages that contain "red boxes," the Red Shoes, "" red berries "...

So if we know who are" the Nosecuantos Dwarfs ", even without knowing exactly how many, we can see:


" the * Dwarfs


Thus so simple, we have refined our search, obtaining results incomparably better than the first query: the first results obtained from the references to "Snow White

and

seven dwarfs" they were looking for.

Try applying this technique to our old problem of "
Among nosedonde and Valdemoro

"

"between * and Valdemoro"

Pinto! :)


Oh, and we have several words undefined in the same query! That is, we can substitute an asterisk all the words of a sentence to doubt "correct." So, if you do not remember exactly what it was that said that the Greek had no destination, we find:


"The 'no destination"

vulgar spirits!

vulgar spirits have no
destination, according to Plato
