Gmail's advanced search uses operators to search your mail for specific pieces of metadata. Things can get geeky very fast, so you'll want to start with some basic searches—like searching for mail from a specific person, for a phrase in the subject, or for emails with attachments. Once you become a power-user, you'll be using Boolean searches, and searching your mail for emails older than a year that you haven't read with attachments larger than 10 megabytes!
If you're logged into your Gmail account, you can click any of the links below to automatically perform the search in your Gmail account.
Searches for attachments in emails by file name, file name + extension, or...
You can search for all attachments of a specific file type by searching for the extension only (e.g., DOC, PDF, XLS, XLSX, PPT, PPTX, etc.)
Folders & Labels
Searches for emails that you have not labeled or moved into a folder. This search will include unlabeled emails in your Inbox, Sent, Trash, and Spam folders since these are not "user" labels—they are automatically assigned system labels.
Read/Unread, Starred, and Important
Searches for the EXACT phrase "mobile app" where both words appear together.
