Anecdotally, both AND and OR work fine for me on dovecot. AND works
for me on gmail, but not OR. I’m no IMAP expert but I thought the
parentheses were allowed. See, e.g.
https://www.limilabs.com/blog/imap-search-requires-parentheses

The parentheses in the OR search are added by
`elmo-imap4-search-generate-or': you could easily modify that function
to remove the parentheses to see if that corrects the issue.

As an aside, with gmail you’re probably better off using X-GM-RAW,
which allows access to gmail’s search.

For example, type V to start a virtual folder, then X-GM-RAW, then
your search condition: from:greg OR from:john (this uses gmail
syntax). You can add "X-GM-RAW" to
`wl-additional-search-condition-fields' for easier completion.

best, Erik
