If you want to improve your Google searches you can find many useful queries on internet and, if have time, you can also attend a specific Google free course.
But just few people know that there are specific queries available for Gmail.
I found some of them casually when I need to search some specific, old emails into my accounts some days ago. Then I discovered that Google itself published a complete list of all the possible queries accepted by Gmail.
I warmly suggest you to spend some minutes reading and exploring all the queries because they are really useful when you use Gmail in a professional way.
Here, I just want to sum-up some of them that, in my experience, are the most common you can use when you are becoming crazy looking for a specific email you sent or received.
The powerful feature is represented by the possibility to mix the different queries to create super-queries that can intercept the “wanted” email or documents in a less than a second.
Here you are defining the time range and Gmail will show all the emails sent or received between the two specified dates.
From or To
Where xyz @zyw.com is the email address you are focusing on.
from:tom OR from:Luis
from:tom OR from:Luis -meeting
In this case you are looking for an email from Tom or (plus) Luis but it hasn’t to contain (- minus) the word “meeting”.
Bcc or CC
Where xyz @zyw are specific email addresses you are looking for.
filename:(jpg OR jpeg OR png)
filename:(doc OR docx OR pdf)
filename:invitation(doc OR docx OR pdf)
And you check into a specific folder. In my case: the Spam folder
Larger or Smaller
Some complex query examples:
from:firstname.lastname@example.org filename:(jpg OR jpeg OR png)
to:email@example.com filename:(doc OR docx OR pdf)
from:firstname.lastname@example.org filename:invitationfrom email@example.com to:firstname.lastname@example.org filename:(doc OR docx OR pdf) subject:meeting
after:2011/10/24 before:2011/11/24 in:spam subject:meeting
