In a brief announcement on the official Gmail blog, Google reported the availability of new advanced search operators that let you find messages by size or date.
“This means, for example, that to find emails larger than 5MB, you can search by size: 'size: 5m' or 'larger: 5m', already to find emails you sent over a year ago, use 'older_than: 1y' ”, published the Gmail team.
To see more advanced search operators in Gmail, you can access this page from the Google Help Center.
