SwiftData query for string in relationship

Question

I'm trying to implement a search function in SwiftUI with SwiftData. I'm struggling to to query for the recognizedText in my DocumentImage. On the list where I want to filter I have several Document that hold n DocumentImage. I found out that it might not work with the #Predicate macro.

But how could I achieve that?

init(searchTerm: String) {
    if !searchTerm.isEmpty {
        let predicate = #Predicate<Document> {
            $0.title.localizedStandardContains(searchTerm)
        }
        _documents = Query(filter: predicate)
    }
}

@Model
final class Document {
    var timestamp = Date.now
    var title = Date.now.dateString + "-" + String(localized: "Untitled")

    @Relationship(deleteRule: .cascade, inverse: \DocumentImage.document)
    var documentImagesStorage: [DocumentImage]? = []

    @Relationship(deleteRule: .cascade, inverse: \Tag.document)
    var tagsStorage: [Tag]? = []

    init(documentImages: [DocumentImage]) {
        self.documentImagesStorage = documentImages
    }
}

@Model
final class DocumentImage {
    var document: Document?

    @Attribute(.externalStorage)
    var imageData: Data = Data()
    var recognizedText: [String]?
    var order: Int?

    init(imageData: Data, recognizedText: [String], order: Int = 0) {
        self.imageData = imageData
        self.recognizedText = recognizedText
        self.order = order
    }
}
