With the new website search feature that's rolling out today, it's possible to search for hashtags, locations, and user accounts directly from a web browser. The new capabilities are designed to make the web experience better complement the mobile browsing experience.
Searching for a location will bring up images from that location alongside a map, while searching for a username will bring up individual accounts and searching for a hashtag will bring up a landing page that shows all images tagged with that label. Search pages display both top posts that have received the most likes and most recent posts.
Today's new web search feature follows a major June iOS update that made it easier to discover content within the Instagram app. That update expanded the "Explore" tab with curated collections of images and enabled the ability to search by location for the first time.
Instagram for iOS can be downloaded from the App Store for free. [Direct Link]
