The Office Developer Tools team snuck a new feature into the RTM version of the tools for Visual Studio 2012. This new feature allows you to deploy apps and actually alter the search schema on the host web. That’s right. You can deploy an app and it will directly change the search configuration on the host. They just released documentation on it a while back, but as usual, I wanted to share my experiences. That and I know you all like screenshots.
What does this feature actually do? Well let’s back up a bit. If you remember back from my post, Search is Everywhere, I mentioned the we now had the ability to export and import search settings. This works at the SSA, site collection, and site level and allows you to move everything from result sources to managed properties from one environment to another. This is big as it lets you finally promote search settings between environments and maintain a true SDLC when it comes to search. Why do we care about search configuration with apps? Well this allows the developer to package up search settings in Visual Studio 2012 and then move them to production without having to do manual steps or use PowerShell. This also means you could include search settings in an app that you would put in the Office Store. It certainly opens up possibilities.
To test this out, go to your source site collection and customize your search settings. In my example, I created a custom result source and some managed properties on our source site. In my example, I actually did this on an on-premises installation of SharePoint 2013.
This particular result source does nothing exciting. It simply limits the search to documents, but it serves as a good example. I’ve also created a managed property mapped to the Author crawled property. You may already know about this part, but I am showing it for a reason.
Now, I am going to export my search settings of my site collection, by going to Site Settings –> Search –> Configuration Export.
At this point, I could manually import the search settings using Configuration Import on another site collection. However, we want to do this from an app. Let’s get started in Visual Studio 2012. Start by creating a new SharePoint-hosted app. Once it is created, add an item to the project and choose Search Configuration.
The next step will ask for the path to your configuration XML file that you exported.
At this point the process is done. It will show you an XML editor with the contents of your search configuration. According to the MSDN documentation, you then need to edit it and set the DeployToParent element to true.
We then need to grant permissions to access the Site Collection. To do this, open AppManifest.xml and then click on Permissions. On this tab, add a scope of Site Collection and set the value to Full Control.
At this point, we are are ready to deploy. In my example, I am taking my search configuration and deploying it to an Office 365 SharePoint Online tenant. When the app deployment completes, you’ll be prompted if you want to trust the app. Trust it and then you should see your app start page.
At this point, you are just going to see you default app start page. There is nothing visible in the application. Go to the Developer Site (or the site collection you deployed to) and go to the Site Settings. Then look at the Result Sources. If everything worked correctly, you should now see your new result source there.
It was successfully deployed. Now what about the managed property? Unfortunately, it is no where to be found. If you go back to Visual Studio and look at your XML, you’ll notice that your managed property definition is no where to be found there either. If you check the source file before you imported it though, you’ll see the definition. After I noticed this particular behavior, I reached out on Twitter and @chakkaradeep reached out to me and told me that managed properties aren’t supported in this deployment model. That made me kind of sad because that’s what I want to deploy the most. I’m sure there is a technical reason though that he’ll explain to me sometime though. You can still deploy managed properties via Configuration Import though which is still a great added feature of SharePoint 2013.
You might be curious if the result source is removed when you uninstall the app. It turns out that the changes are indeed removed when you uninstall.
Aside from the managed properties not being available, this is still a pretty cool feature and it has me thinking about some new things I can do that I didn’t think were possible before. I’m pretty excited to work with it more.

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com), moderated by Ashar Baig, Research Director, Cloud, at Gigaom Research, Nate Gordon, Director of T...
