FTS5TokenizerDescriptor

The tokenizer components

// ["unicode61"]
FTS5TokenizerDescriptor.unicode61().components

// ["unicode61", "remove_diacritics", "0"]
FTS5TokenizerDescriptor.unicode61(removeDiacritics: false)).components

Creates an FTS5 tokenizer descriptor.

db.create(virtualTable: "book", using: FTS5()) { t in
    let tokenizer = FTS5TokenizerDescriptor(components: ["porter", "unicode61", "remove_diacritics", "0"])
    t.tokenizer = tokenizer
}

The “ascii” tokenizer

db.create(virtualTable: "book", using: FTS5()) { t in
    t.tokenizer = .ascii()
}

An “unicode61” tokenizer

db.create(virtualTable: "book", using: FTS5()) { t in
    t.tokenizer = .unicode61()
}
