Gmail’s search is getting a significant update that will allow users to more easily narrow results to help them find a specific email. Before today, users could type in search filters by hand (e.g. label:work, has:attachment, from:marketing@company.com, etc.) or use the drop-down box to perform an advanced search. But these options were less obvious, cumbersome and therefore under-utilized by many Gmail users. With the upgraded version of Gmail search, new filters — which Google calls “search chips” — will appear directly below the search box for simple, one-click access.

At launch, there are a variety of filters available, including those that will help you narrow down emails by sender, whether or not emails have an attachment, by time frame, and more. You also can use the new filters to exclude certain types of search results — like those that are calendar updates or chats, for example. And you can specify emails by attachment type, such as text, spreadsheet or PDF.
