Are you just using the built-in search engine? I just tried it with your search string, without double quotes, with no results being found at all. As I've seen stated several times in meta, this search engine doesn't always work well.
You should consider trying https://approach0.xyz/search/ . As Martin Sleziak's comment states, it's optimized for searching formulas, but you may find it also useful for other types of searches, even if just as a secondary check. I just tried using Approach0, with it coming up with $40$ pages of results using your search text, both with & without using double quotes. I'm not familiar with Approach0, but you may wish to check its user guide to see how you can best use it. Note doing a search of "approach0" (without double-quotes) using the built-in search on meta returned $21$ results, such as Announcing a third-party search engine for Math StackExchange., from about $3$ years ago, that introduces this new option & gives some basic details about it.
Another option to consider is to use Google, but restrict it's searches to the Math SE site (and, as Martin Sleziak's comment states, you can also restrict the results to within a specific time period). You can do this by prepending your search phrase with "site:" and the site's URL, e.g., as follows:
site:https://math.stackexchange.com hyperbolic William David crochet geometry
However, when I tried this, I got back no results. However, if you remove some search terms (e.g., the last $2$), you will likely got some results (e.g., $22$ in my test without the last $2$ terms). Also, it's handy to keep this in mind when you're doing other such searches since Google's search algorithm works differently than either the built-in search or Approach0, so I suspect it can sometimes find posts better than either of the $2$ other options.
In addition, Google can search the meta site. It also supports sub-levels so, for example, you can search only the questions (by using "site:https://math.stackexchange.com/questions"), answers (by using "site:https://math.stackexchange.com/a"), only the users (by using "site:https://math.stackexchange.com/users", with a search for my surname finding $4$ most relevant results), etc.
