This is incredible: Google Has a Secret Reference Desk. Here’s How to Use It. I knew some of these but not all, e.g. verbatim mode “returns results for exactly what you typed, stripped of personalization and synonym-swapping.” https://cardcatalogforlife.substack.com/p/google-has-a-secret-reference-desk
Google Has a Secret Reference Desk. Here's How to Use It.

40 Google features to find exactly what you need, the alternative search engines that do things Google won't, and the reference desk framework underneath all of it.

@kottke well it WAS a secret
@BoredomFestival in fact, it never was a secret. @kottke

@kottke ha, had a book once:

"Google Hacks" Still available with all that stuff.

Google Hacks, 3rd Edition

Everyone knows that Google lets you search billions of web pages. But few people realize that Google also gives you hundreds of cool ways to organize and play with information.... - Selection from Google Hacks, 3rd Edition [Book]

@kottke Almost all my Google searches include -youtube because I only want words and maybe a diagram.
@kottke tbh that is 2010 knowledge and it doesn't work properly anymore in 2026 because Google actively made the search worse for several shitty reasons. Instead it ignores parts and also inserts ads where it can

@kottke There was a time when +asearchterm made it mandatory.

Google killed that syntax so hard that other search engines dropped it.

I miss that time.

@NegativeK @kottke
And they killed it just for Google+ where usernames were supposed to be: +coolguy etc. What a waste.
@Klassika @NegativeK @kottke have never forgiven Google+ for this!
@NegativeK There was a time when *including a search term* made that term mandatory.
@kottke Is there a version for DuckDuckGo? I gave up all things google a while back. Although I don't think it was moochual

@kottke

This IS incredibly! Everyone should read this.

@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.

@kottke

I use site: and inurl: often.

I still have trouble remembering to use "{search_term}" instead of +{search_term}.

I'm not sure if -{search_exclude_term} ever worked.

@kottke

Many thanks.

I am using Bing and Ecosia (Google) at the moment.
Your info is far more helpful, worth passing on? For sure.
