Gmail's filters are either very weak or I don't understand, how to create just a bit more complex ones.
In particular, how can I create a filter, that will match:
messages in SPAM folder (as well as in others or only in SPAM folder),
messages, that contain specified keyword in many fields (i.e.
Fromfield and message's body).
I'm able to match messages, that contain more than one keyword in given field (for example, to match many keywords in
From field, I use
one OR two OR three). But, can I write one filter, that will match these keywords in both
From field and message's body? So, it will apply given filter rule, no matter, if keyword was found in this or that field? Or do I have to write separate filters for each field, which I want to search for matching keywords?
