Opera Mail Search
One of my accounts gets clogged with a lot of mail from a list. some non list mail can easily be overlooked.
I would love a Negative search term.
e.g. if all the list mails contain the string "[abc]", the if I typed a search saying "-[abc]", or "NOT[abc]"
then all other mails would be shown.
Is this possible? And, if not, could the programmers add the feature?
I don't know if its possible, it very well may be, but if it isn't it won't be added. Opera Mail's development has been discontinued.
You can create a label that *matches what you want to hide* (use regex rule if necessary). Then, you can set "hide these messages from other views" in the properties for the label. Then, those messages won't show in other views as long as you have "show hidden" unchecked for those views.
To get to the show settings for a view, click the "settings for this view" icon on the message list toolbar.
Now, if you perform a search on a view with the search field, when the results show up,according to Opera, the result list will actually be a different view. You can then make sure "show hidden" is unchecked for that view. As in, you might have "show hidden" checked for a view, search in that view and uncheck "show hidden" for the result view. I just forget if the show settings for a search result view are saved when you change them or if you have to do that every time.
Anyway, that's something you can try.
