But if it links to the B9GDSIG series refrigerator, which has the 240v H and 120v Y subtypes, then it would be correct in suggesting that?

Same with error messages - they often have timestamps, or local object IDs/memory addresses, which you also want to be fuzzy-matched.

I think the issue is the de-emphasis of "power" modifiers for google - it's less obvious how to say "This part of the string needs exact match, this can be fuzzy"
