Thanks.

This should explain what kind of "emoji names" the feature accepts.
It is entirely unclear from the text.

Likewise here.  The NEWS entry doesn't even mention that Emoji are
specified by their names.

  "Read and Emoji name and add it to the search string."

Likewise here, the doc string should clarify what kind of names are
acceptable.  I would also mention that completion is provided while
typing the name.
