Everyone has long known that Google can be used to check the spelling of a word, if you doubt the choice between the two options. Enough to drive both options into the search and look at the number of pages found. For example: quantity (173 000 000) and quantity (1 330 000) - it is obvious that the correct variant is quantity.
Today I discovered a new use of this feature of Google. I write the text and there the phrase "We had had always ..." . But do not really like the sound. You can also write like this: "We have always had ..." or even like this: "We always have had ..." . How correct and melodious? We drive in all 3 phrases, one by one, into Google, and we find that the most frequently used, and therefore correct, is “We have always had ...” .
Who else knows some useful ways to use Google search? :)
