On the page: "https://book.simply-logical.space/src/text/1_part_i/1.1.html"

If I take the quote: "At the beginning of this section, we posed the question: can we show that our two definitions of the nearby-relation are equivalent?"

Searching on google lead to 2 dead link, and another website republishing the book as pdf.

Others search engines give me the link of the page I got the quote from, as the first result.

That's not a sign that quote search doesn't work. In fact, the opposite. The pages you get all appear to have that really long quoted phrase. Instead, it's a sign we don't have one particular page with that quote indexed. Certainly better if we did have that page included in our index, of course. I'll pass it on.

Two of three are dead links, so not really.

While indeed google doesn't look to have indexed this particular page, it looks like others search engine successfuly indexed it.

The "relevant"(where this verbatim string came from) result looks like a pdf dump websites, which is less relevant to what I want.

I also get the dead link, and the 2nd link is now this comment :)

But a false negative (not getting a page that has the phrase) isn't the same as a false positive (getting a page that doesn't have the phrase), which is what the GP is talking about.
