@kottke unfortunately the features vary in their support - e.g. there was a good chunk of time (a couple years maybe?) where quotes didn't ensure exact matches, and you had to +word or +"multiple words" (which didn't always work) to get precision again. I've also had negative and site matches (and especially negative site matches) fail, though it has consistently at least down-ranked those terms. it depends on how "helpful" Google is feeling / who wants a promotion this quarter. generally speaking though yea, these are all super useful, and you can get many of them without needing to remember terms if you use their "advanced search" page: https://www.google.com/advanced_search the advanced search page has also worked consistently for me, unlike special terms in the general UI.
