Hi,
I would look to look for all emails from a colleague jongho. I tried:
from:jongho attachment:pdf
which seems to do as I wanted.
To understand more, what does the following search for?
from:jongho attachment:.*pdf
I know it is incorrect as the results tell me, but what exactly does it do?
Also, how does the first one above know that I want only PDF
attachments and not an attachment called "pdformula.txt" ?
Kind regards,
Xu
