I may have misunderstood current behavior or the future behavior, but when I deeply read the match type descriptions last month, I was led to believe that phrase required that the user's entry have a contiguous set of words matching the meaning of the phrase: i.e., no intervening concepts. So, keyword "used honda accord" would not match "preowned honda civic or accord" but would match "preowned honda accord or civic" because in the former "civic" interrupts the phrase. Broad modified, otoh, didn't require contiguity so it would match either.
If I was correct, then what is the new behavior? That is, please confirm it will continue to match both user queries.
