I have some email contacts who use two (or three) different email addresses. Sometimes contacts also change emails over time.
This confuses things when I want to search for emails from them in my Gmail online interface.
Right now I use a search string like so:
from: email@example.com OR foo_other@bar_other.com
Is there any easier way of doing this by setting maybe something like an alias? It's also hard to keep remembering who are these people who use multiple emails and what those emails are.
How does one tell Gmail succinctly that search on multiple addresses when I mention a certain person?
Any other tricks or hacks that I am missing?
