E avresti vinto! :)
2.237.000 "campo di calcio" vs. 2.040.000 "campo da calcio", in una ricerca
Google "Verbatim".
Limitando la ricerca ai siti *.it, la vittoria sarebbe stata ancora più
netta.
1.470.000 vs 987.000
Per evitare che Google dia numeri totalmente sballati, occorre
1. delimitare l'espressione tra virgolette, altrimenti Google non cerca
l'espressione ma le singole parole,
e
2. usare lo strumento di ricerca Verbatim di Google, non una ricerca Google
generica.
Google Verbatim fa una ricerca letterale.
Una ricerca generica, al contrario, include alcune alternative definite
dagli algoritmi di Google.
Dalle spiegazioni dello strumento Verbatim di Google Search:

Verbatim tool
With the Verbatim tool, you can search using the exact keywords you typed.
The searches you make on Google are usually improved to help minimize your
time spent searching and get you the information you really want. Here are
some of the improvements Google makes:
suggest spelling corrections and alternative spellings
personalize your search by using information such as sites you’ve visited
before
include synonyms of your search terms to find related results
find results that match similar terms to those in your query
search for words with the same stem, like "running" when you search for [
run ]
But, for the occasions when you want to search for very specific words, you
can use the Verbatim tool so that Google searches using the exact words you
entered. Here's how:
Click More search tools on the left side of the search results page.
Click Verbatim.
Type your search terms into the search box and type Enter.

Sometimes Google's algorithms don't know better, or at least that's the
thought behind "verbatim", a new Google Search feature announced on
Wednesday.
In verbatim mode, which can be accessed by clicking "Show search options" in
the left-hand column of a Google results page, Google will not make any of
its "normal improvements" to your search and will only look for the literal
words you type into the search bar. According to the Google blog, the
improvements that Google will not make when searching in verbatim include
the following:
- making automatic spelling corrections
- personalizing your search by using information such as sites you’ve
visited before
- including synonyms of your search terms (matching “car” when you search
[automotive])
- finding results that match similar terms to those in your query (finding
results related to “floral delivery” when you search [flower shops])
- searching for words with the same stem like “running” when you’ve typed
[run]
- making some of your terms optional, like “circa” in [the scarecrow circa
1963]
It used to be that a "+" between keywords would denote an exact search, but
in October it was reported that Google had quietly dispensed with the rarely
and incorrectly used symbol in favor of double quotes around keywords.
Some said the "+" search operator was replaced because Google wanted to use
it in Google+ profile searches without confusion.
Regardless of the reason, there was a niche uproar over the change.
According to Wired.com, blogger Andy Baio tweeted, "Google phased out the +
operator yesterday, which means I now have to 'quote' 'every' 'term' 'like'
'this'. Nobody else finds this annoying?" A Google employee quickly
responded to say they were working on a fix. Today's announcement of
Verbatim, which Google calls a "more deliberate" way to search exact terms,
appears to be that fix.
Baio was apparently pleased. Following the verbatim announcement, he
tweeted, "It feels strange to have influenced Google, and I'm frankly
astonished at how quick the change was introduced. Nice work."
