Merge requests search keyword "is one of" is missing

How to use “is one of” in merge requests search ?

In the merge requests search, it is possible to search for all MR :

  • of one author: author = @author.username
  • of all authors except one: author != @author.username

but it is not possible to search for MR of several authors.

We have several teams using the same repository (not ideal I know), and I’d like to filter the MR only on authors from one team.

Why is there not the “is one of” keyword that is available in the issue search for example ?

Thank you very much for any insights.
