This sample shows how to add, update, and retrieve items and properties from the indexer. 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
Uses the UpdateAsync method to update an item and the DeleteAsync, DeleteMultipleAsync, and DeleteAllAsync methods to remove content from the system index.
-
Get items from the system index by using a query
Uses the CreateQuery and GetAsync methods to retrieve items from the system index.
-
Check the revision number of the indexer
Uses the Revision property and the app's LocalSettings to check if the app's expected revision number matches the actual index revision number.
-
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
Uses the CreateFileQuery and CreateFileQueryWithOptions methods to query the system index for file properties.
