Another feature that we must wait 7 years to made? OMG, everything I’m looking for that I’m missing is already reported years ago and never made.
EDIT: well, at least something was made, there is option for “all text fields” in search folders that may be use as “or” with commas; seems to work very well.
You can easily simulate OR and AND. For instance from:*tom*,*jay* will return all messages that were sent by an email address containing tom or jay. From:*tom* from *jay* will return any email where the sending address contains both tom and jay.
