There's no syntax of which I'm aware which tells Google to not "correct" or expand the results.

When I'm seeking specific matches, I'm seeking really fucking specific matches. Google annoy me to no end.

I believe it was possible in the past using URL parameters (e.g. complete=0 to disable auto-suggest) but it does not seem to work anymore.

Here it was documented in 2012:

There are (or at least were) others with related effects.

Boolean search would be wonderful

+word

It used to force to search the word exactly as written.

"Used to" is the operative phrase. That was among the negative consequences of Google+, as +<term> notation apparently was going to be reserved or repurposed for that somehow, but never was.

I've done some large-scale searching where the most relevant detail is how many results are returned, most particularly for a specific domain. (For which, incidentally, there's no handy mechanism to accomplish, so it's <array of terms> * <array of domains>, and multiplicative explosion of searches, plus about a 45s timeout per query to avoid triggering bot defenses by Google.

Such as this:

The plus/+ notation has been removed. You must know surround the term in quotes "word".

I wish there was a way to use both Verbatim and Date Range at the same time: you end up having to choose between recent but irrelevant results, or relevant but obsolete results.
