I just had a good occasion to test this.
I wanted to find pump up the brakes and entering just that
gave 7.2 meg hits with my exact phrase not first, fourth, or fifth.
They didn't have the word up.
Using pump up up up the brakes I got 3.46 meg hits with all
the words** in the first 7 hits, Stopped looking at that point. But
by hit 6, they were not all in a row. Clearly better than the first
method, above. **Not counting "the".
Using pump "up" the brakes I got 3.57 meg hits, no "up" in hit
1, 3, or 5. At least not in the excerpt.
Using "pump up the brakes" I got only 32,700 hits with the first
55 hits in a row with all 4 (four) words, and I got tired of counting at
that point.
C4. using the word 3 times clearly helps, but Arfa has you beat.
Arfa, I tested quotes verus no quotes years ago but years after google
started and I got the same results with quotes or without. But either
I didn't choose the right search terms, or they've changed things. I
think I didn't choose the right terms, although maybe when they got rid
of + they improved "words". ??
