Despite Google’s dominance and expertise in search-related algorithms, it’s often hard to find a particular email in Gmail. The company is now trying to solve this problem with a new filter feature called “Search Chips.”

Here’s how it works: After you search for an email with a keyword, you’ll see filter buttons on top of the search result such as “Has attachment,” “Exclude chats,” and a date picker. You can even pick the type of attachments such as text, PDF, or image. These buttons or “Chips” will help you narrow down search results.
