Re: I think you forgot one
Actually, I find that the first ten pages invariably turn out to be either from Pinterest (which I'd prefer banned from my results in perpetuity considering a) it's always utterly irrelevant b) wants me to register even to give me the time of the day), Alibaba (for which I, not being an en-gros merchant with Eastern proclivities have precisely zero use, ever) or some site aggregating "best deals" from half of the retailers on the internet (bonus: if, accidentally, it advertises exactly the item I'm looking for, it turns out the affiliate link is expired or the item is no longer sold by the actual retailer who pretends to have never even heard of it).
Oh, and the best part? As far as I know, there is no such thing as "operator" or "boolean", at least not on Google. The only thing they let you do is put your terms in quotes to (hopefully) search for exact expression. "Plus" means nothing. "AND" means nothing (guess what, "OR" works - because it doesn't impede Googles ability to shove MORE unrelated garbage down your throat - but it's useless, because it's on by default either way). You wanted BOTH your search terms mandatory? Tough luck, sunshine, we don't have the technology for that. Not any more...
