Has anyone been using Google autofill to find keywords or search phrases?

I'm not sure how long ago Google implemented the autofill part of their search box, but I just thought that maybe it would be a good way to get commonly searched terms or phrases that article writers or website owners can put into their webpages.

I am not quite sure exactly yet how best to use this data. Once you start to enter some words, the autofill will present a list of common search terms and the number of results for those words. If one were to make an article trying to use one of these terms, which selection would be best to use first.

For example, if I type in "Why am I" into Google.com, I get a list of results similar to this:

Why am I:

-so tired 6.8 million results
-always tired 1.0 million results
-here 159 million results
-always cold 4.2 million results
-not losing weight 1/2 million results

My assumption here is that the last one 'Why am I not losing weight' would be the best choice. First off because it comes up in the search list, that means people often search for this phrase, but at the same time the amount of webpage results is the lowest. This means that there is less competition, at least compared to the others.

Would it still be worth trying to get a webpage ranked titled "Why am I not losing weight"? It probably would be very difficult to attain the top ten.

There is also the fact that the number of page results for those keywords doesn't necessarily correspond to the number of searches for those keywords. I am making an assumption that they would be linked enough so that the keyword phrase with the most page results would be suggestive of the highest searched for keyword phrase.

To give another example, if we look at the autofill for "Why is" we get as the first result "Why is the sky blue". A quick check at the first few listings of that search will get you to pages that have existed since 1997. Fat chance bumping those off the list. I can't imagine how many links point to those pages.

Obviously we have to be selective in our keyword phrase choosing so as not to waste time in writing an article that no one will ever see, unless someone browses to the 10th page of results..

I am going to try to write a few articles using phrases that populate less results to see if I can get on the first page of google results. I know it is possible, as some of my other articles here have made it to the top of Google within four days of being written.

I'll post an update in a few weeks.
