Yes, please! But for a slightly different reason.

I'm finding that I sometimes get a ton of utterly irrelevant entries from Bing clogging the results based on the first search term, and ignoring the rest of the query.

I can dodge it to a certain degree if I carefully order my query from least to most common terms, but it's a headache, involves trial and error, and I suspect I'll find similar idiosyncracies (or conflicts) with other engines I'm less familiar with - it feels like debugging Perl code in the 90s. And, really, Bing is kinda garbage anyhow - I'd rather just be able to say -!bing (or anywhere else misbehaving) and get it out of the way.

As a recent example:
Query: sweet "gyoza sauce" "recipe"

Result: The first nine entries are from Bing. Eight of those are for definitions of the word "sweet", and the other is Wikipedia's page for the 70s British glam band The Sweet (who were never notable for their Asian cooking prowess, unless I missed that album).
