Out of curiosity, I noticed (as I mentioned in a reply to your sibling) I could produce unrelated results by fiddling with the region; does changing region do anything for you?
Just tried to test it out and I'm now seeing correct results when I set the region to 'US' and an empty list of results when using my own region. This is not at all what I was seeing earlier.
That isn't how the quote feature is supposed to work. I just tried putting the individual keywords in quotes ("lowes" "pet" "bedding") and it works exactly like you would expect.
How is it supposed to work? I expect to see only those results that contain an exact match on the entire phrase between the quotes but perhaps I've misunderstood?
