The [[https://docs.arduino.cc/language-reference/](https://docs.arduino.cc/language-reference/)]([https://Language](https://Language) Reference) does not seem to have the String functions available. For example, when I type "substring" into the search bar in Documentation, the first example takes me to the built-in example. I checked the Language Reference, and sure enough, there is no String category.

And you can find it under variables; needs a bit of scrolling.

My docs has it, both kinds.

I find the search facility to be somewhat painful. I am sure it found it, but where is the result?

The key is to change the search tab from "On Docs" to "In Language Reference":

&nbsp;

Interestingly, if one instead clicks the first result under "On Docs", the [String substring Function built-in example tutorial](https://docs.arduino.cc/built-in-examples/strings/StringSubstring) that is opened does include a hyperlink to the Language Reference article on [`String()` objects](https://docs.arduino.cc/language-reference/en/variables/data-types/stringobject/), but it is a dead link (because it points to `https://docs.arduino.cc/language-reference/en/variables/data-types/StringObject/` instead of `https://docs.arduino.cc/language-reference/en/variables/data-types/stringObject/`).
