Google Search for Android got a major update that includes pulling search results from apps where they are relevant. Earlier search results will open web pages, now with the app integration your search queries can directly take you to the app your results are there. An example posted on Google Blog shows when you search for a movie results are shown from IMDB, when you click on those results you will be taken straight to inside the app. There is a open in app button which can guide you to the app.
This means now users searching in Google search can go to the relevant app at the click of a button, if that app is installed of course. Currently only a handful of apps support this feature and the update for Google search is rolling out for everyone. This in-app search will work when using the Google Search application on any Android phone, Chrome or Android browser.
Google explains some time the results you are looking for may be an app, in those situations Google will pull up results from Play Store and you can go and download the app. The list of apps that support this feature will increase over time, but currently only these apps are supported: AllTrails, Allthecooks, Beautylish, Etsy, Expedia, Flixster, Healthtap, IMDb, Moviefone, Newegg, OpenTable, Trulia, and Wikipedia. If you are a developer and want to know how to implement this feature look here.
