Google has announced the addition of 24 new apps to its integrated search feature, which allows users to find a relevant topic on Google Search within an installed app on the device. If the app isn’t installed on the Android phone/tablet, Search will give you a link to the Play Store to download it directly from there. Several popular apps are supported by this feature and 24 new applications will now be included as well.
Apps like 500px, AOL, BigOven, Bleacher Report, Booking.com, Eventbrite, Glassdoor, Goodreads, Huffington Post, Merriam-Webster, Pinterest, Realtor.com, Seeking Alpha, TalkAndroid, TheFreeDictionary, The Journal, TripAdvisor, Tumblr, Urbanspoon, Wattpad, Yellow Pages, Zagat, Zappos and Zillow are the freshly added ones with this feature.
These changes will occur on the server side and should be spotted on your Android device without an app update, so you can expect to start seeing them by today. They will allow you to get better access to content when you search for something, as apps are tailored to work specifically with them. This app integration is one of those Search features that has existed for quite a while but often goes unnoticed.
