gh give a OR to issue search

but gh adresses

1. only issues
2. only labels (as concatenate by "OR")

https://github.blog/changelog/2021-08-02-search-issues-by-label-using-logical-or/

You can now search issues by label using logical OR. Simply use a comma to separate the labels. For example label:"good first issue",bug will list all issues with a label good first issue or bug.

example:

There is no way to combine AND and OR operators that I have found. So I don't think it is possible to find open PRs from any of several authors for a single repo.

The NOT operator can be used to exclude strings: https://help.github.com/articles/understanding-the-search-syntax/
