I have a SwiftUI document-based app that for the sake of this discussion stores accounting information: chart of accounts, transactions, etc. Each document is backed by a SwiftData DB.
I'd like to incorporate search into the app so that users can find transactions matching certain criteria, so I went to Core Spotlight. Indexing & search within the app seem to work well.
The issue is that Spotlight APIs appear to be App based & not Document based. I can't find a way to separate Spotlight data by document.
I've tried having each document maintain a UUID as a document-specific identifier and include the identifier in every CSSearchableItem. When performing a query I filter the results with CSUserQueryContext.filterQueries that filter by the document identifier. That works to limit results to the specific file for search operations.
Index updates via CSSearchableIndexDelegate.reindex* methods seem to be App-centric. A user may have file #1 open, but the delegate is being asked to update CSSearchableItems for IDs in other files.
- Is there a proper way to use Spotlight for in-app search with a document-based app?
- Is there a way to keep Spotlight-indexed data local within the app & not make it available across the system? I.e. I'd like to search within the app only. System-level searches should not surface this data.
