In your other thread, I have already suggested some much better search terms (and some actual links) to research the question you have been asking. “Cheerio floaters” is not working for you because that is not what other people call the phenomenon.
The days of Googlewhacking - finding a pair of words for which a simple Google search returns just one hit - are now long gone. These days, if you enter multiple words into Google, if it can’t find any pages (or any more pagers after it has found a few) with all those words, it will generally return pages with just some of them. I may even return pages with high PageRank, but that only contain some of the words, ahead of low PageRank pages with all of them, or pages that contain some of the words several times ahead of pages that contain them all just once. There are some tricks you can use to try to stop it doing this sort of thing, such as enclosing each word, separately, in quotes, but in my experience this does not work very reliably. The + operator, which used to work well, will now find you only material on Google+. What is more, Google will often return different results on different machines, depending on such things as where your IP address seems to be located, and what cookies it has on your machine. Furthermore, the search algorithm is constantly tweaked and sometimes quite significantly changed, so Google may well not return the same results for the same person using the same computer from one day to the next. Google’s ability to find a page relevant to a carelessly constructed, casual search, ha improved greatly over the past few years; its ability to perform a precise, specific search has turned to shit.
On the other hand, if you enclose several words within a single pair of quote marks, so that Google searches for that as a “phrase”, you will easily come up witha string of words that return zero results. I just tried searching for “banana football chasm”, the first three unrelated words that sprang to mind, and. as expected, got no hits for that ‘phrase’. Google nevertheless decided to show me the results of searching for banana football chasm without quotes, for which it claimed to have found “about 26,100,000 results”, but even the first of them contained only two of the words. Perhaps there are pages with all three further down the list, but I am not going to look all through searching for them.
