Zeb asked, "what does ."About 43.500.000 results (0,44 seconds)"..mean, please."
"About n results" are the number of matches the search engine company has in their database for the keyword [or phrase] you searched for.
"n seconds" is the how long it took for the search engine to give you an answer.
Be aware that even though a search engine will tell you it has found forty-three million results, it will only show you about one thousand of them. If you went through all the results displayed you would find that often before you reach page 100 the search engine will stop giving you results.
Also you should no that just because Google (for example) says it has forty-three million results does not mean that there are precisely forty-three million XJW sites (for example) on the internet. The internet is HUGE and it is unregulated. Search engine companies like Google employ the service of "Cleaners" (censors) who remove inappropriate search results from the DATABASE - not from the internet - so they can't be accused of promoting child porn or snuff movie (actual murder) sites. These exist but you can't find them by the usual means.
You will also often find that some of your search results are repeated a couple of times or more. The bottom line is that "forty-three million" is essentially a meaningless number. If they said they had "speen squared times minus i" results it would be almost as helpful, unless you are doing some kind of geeky results-measuring contest.
A recent TV show on PBS in the USA dealt with the matter of "The Cleaners." It is very interesting, and you might be able to view it here;

The people who do this work are poorly prepared for their jobs, I think, and some show signs of PTSD after viewing material they find repugnant for a few hours. Others find a new "secret vice" and enjoy some of the subjects with which they were previously unfamiliar.
The world is wonderful, brilliant, full of hope and depraved, dark, abusive and uncaring at the same time.
