Content indexer sample
Shows how to add, update, and retrieve items and properties from the indexer.
Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.
Two methods of doing so are demonstrated. The first is using the ContentIndexer APIs to directly interface with the indexer. The second is writing .appcontent-ms files, which contain information to be indexed that the indexer will pick up once the file has been written.
The sample demonstrates these tasks:
Add an item to the system index
Uses the AddAsync method to make app content searchable in the system index.
Update and delete items in the index
Get items from the system index by using a query
Check the revision number of the indexer
Add app content files to be indexed
Copies app-specific files to the app's LocalState\Indexed folder to make app content searchable in the system index.
Remove file content from the system index
Deletes app-specific files from the app's LocalState\Indexed folder to remove app content from the system index.
Get indexed file properties
Note The Windows universal samples require Visual Studio 2017 to build and Windows 10 to execute.
