Instance Method

searchableIndex(_:reindexAllSearchableItemsWithAcknowledgementHandler:)

Tells the delegate to reindex all searchable data and clear all local state information.

Required.

Declaration

func searchableIndex(_ searchableIndex: CSSearchableIndex, reindexAllSearchableItemsWithAcknowledgementHandler acknowledgementHandler: @escaping () -> Void)

Parameters

searchableIndex

The index in which to reindex the searchable data. The delegate or app extension should pass searchableIndex to indexSearchableItems(_:completionHandler:).

acknowledgementHandler

The handler to call after all client state has been saved. Note that if the app passes client state information in a batch (for example, by calling endBatch(withClientState:completionHandler:)), the acknowledgement handler can be called immediately.

The delegate or app extension must call the acknowledgement handler after all client state information has been saved, so that the indexer can call this method again in case of a crash.

Discussion

Typically, the index tells the delegate to reindex its searchable data and clear local state when the index has been lost. An app extension should not use the index passed in searchableIndex when a custom data protection class is needed.
