I took the term from the Unicode website:
https://unicode.org/emoji/charts/full-emoji-list.html (last column).
Those are the strings that emoji-search autocompletes.

I see your point, but I don't know a better term to refer to an "Emoji
name".  I think people using other platforms with Emoji support, like a
mobile phone, are used to type things like "grinning face" in a text box
and see the corresponding Emoji suggestion to replace the text with,
right in the phone's keyboard.

Linking to https://unicode.org/emoji/charts/full-emoji-list.html from
the docstring (if the information there is considered stable) might be a
good idea.
