Hi, I have encountered this a few times already (without remembering other references):  
I just searched for “thread” in the [Optimizations.jl documentation](https://docs.sciml.ai/Optimization/stable/), giving two results:

 ![search for thread in optimizations.jl](https://global.discourse-cdn.com/julialang/original/3X/1/c/1cd9304c69e491844cd2e2a6ce13d360799339a3.png)

However, after clicking on the first page I find that there is no mention of “thread” on this page:

 ![False positive](https://global.discourse-cdn.com/julialang/original/3X/4/7/47d4ea2b6271f333512506deb447e52798db2d27.jpeg)

Is this a known bug or what is happening here? Is this something everyone encounters sometimes?

I keep coming across this problem in random package documentations, does anyone know what is going on?

I reported this a while ago as a bug. I can’t remember the issue number, from the top of my head.

Edit: [Overly eager search-result reporting · Issue #48748 · JuliaLang/julia](https://github.com/JuliaLang/julia/issues/48748)

That issue was closed as a duplicate of another issue (on the Documenter repo), but that one doesn’t have any mention of this particular issue: a search term showing supposed results that don’t actually contain the term. It only has multiple cases of the opposite, i.e. a search term being present in the page but not showing up in the results. @fgerick it’s worth adding the Optimizations.jl “threads” case (and any other similar instances you can remember in other docs) as a comment on the [Documenter issue](https://github.com/JuliaDocs/Documenter.jl/issues/1457) to make sure those are also tested for.

As seen towards the end of that thread, there is a PR that’s intended to fix issues related to search terms:

but it’s not clear whether it fixes this particular issue. It’s a pretty bizarre issue, the only cause I can think of for it is that there is some fuzzy search that’s being overly liberal, and matching eg. “three” with “thread”. That’s just a conjecture though, it’s worth bringing up on Github and maybe in the Slack `#documentation` channel.

The fuzzy search is exceedingly eager. For instance, my name is apparently all over the manual:
