ContentType
Setting this property on an element indicates that the element’s content is treated as a base64 encoding of the specified MIME type / content type and is indexed using the handler for that content type.

Examples
This example shows a simple appcontent-ms file that describes an item named "Sample 1".
Notice that the file contains elements not defined by the appcontent-ms schema: IndexerSampleInformation and IndexerSampleSpecificElement. Your appcontent-ms file must have a root node that encapsulates all the data to be indexed, but you can name that node anything you want.
<?xml version="1.0" encoding="utf-8"?>
<IndexerSampleInformation>
<Properties xmlns="http://schemas.microsoft.com/Search/2013/ApplicationContent">
<Name>Sample 1</Name>
<Keywords>
<Keyword xml:lang="en-US">Sample 1 - keyword 1</Keyword>
<Keyword>Sample 1 - keyword 2</Keyword>
</Keywords>
<Comment>Sample 1 comment</Comment>
<AdditionalProperties>
<Property Key="System.Title">Sample 1 Title</Property>

</Properties>
<IndexerSampleSpecificElement sc:IndexableContent="true"
xmlns:sc="http://schemas.microsoft.com/Search/2013/ApplicationContent">
The text included here will be indexed, enabling full-text search.
</IndexerSampleSpecificElement>
</IndexerSampleInformation>
You can even tell Windows Search to index the content of arbitrary elements. Just use the IndexableContent attribute to tell Search to index the content. In the preceding example, Windows Search will index the content of the IndexerSampleSpecificElement because the IndexableContent attribute is set to true:
<IndexerSampleSpecificElement sc:IndexableContent="true"
xmlns:sc="http://schemas.microsoft.com/Search/2013/ApplicationContent">
The text included here will be indexed, enabling full-text search.
</IndexerSampleSpecificElement>
Search will treat the content as text content by default; if the content is base64, use the ContentType attribute to specify the MIME type.
The next example shows how to copy an appcontent-ms file to your app's LocalFolder\Indexed folder. The code copies any files it finds in the app's appcontent-ms folder to the LocalFolder\Indexed folder. (You can also create new appcontent-ms files directly in the Indexed folder rather than copying them from another location.)
/// <summary>
/// For the purposes of this sample, the appcontent-ms files are stored in an "appcontent-ms" folder in the
/// install directory. These are then copied into the app's "LocalState\Indexed" folder, which exposes them
/// to the indexer.
/// </summary>
public async static Task<string> AddAppContentFilesToIndexedFolder()
{
var localFolder = Windows.Storage.ApplicationData.Current.LocalFolder;
var installDirectory = Windows.ApplicationModel.Package.Current.InstalledLocation;
var outputString = "Items added to the \"Indexed\" folder:";
var appContentFolder = await installDirectory.GetFolderAsync("appcontent-ms");
var indexedFolder = await localFolder.CreateFolderAsync(
"Indexed", Windows.Storage.CreationCollisionOption.OpenIfExists);
var files = await appContentFolder.GetFilesAsync();
foreach (var file in files)
{
outputString += "\n" + file.DisplayName + file.FileType;
await file.CopyAsync(indexedFolder,
file.Name, Windows.Storage.NameCollisionOption.ReplaceExisting);
}
return outputString;

// For the purposes of this sample, the appcontent-ms files are stored in an "appcontent-ms" folder

function _addAppContentFilesToIndexedFolder() {
var localFolder = appData.localFolder,
appcontentFolder,
indexedFolder,
installDirectory = Windows.ApplicationModel.Package.current.installedLocation;
var output = "Items added to the \"Indexed\" folder:\n";
installDirectory.getFolderAsync("appcontent-ms").then(function (retrievedAppcontentFolder) {

var promiseArray = [];
for (var i = 0, len = files.length; i < len; i++) {
promiseArray[i] = files[i].copyAsync(indexedFolder,
files[i].name, Windows.Storage.NameCollisionOption.replaceExisting);
output += files[i].displayName + files[i].fileType;
if (i < len - 1) {

}
