FTS5TableDefinition
public final class FTS5TableDefinition
The FTS5TableDefinition class lets you define columns of a FTS5 virtual table.
You don’t create instances of this class. Instead, you use the Database
create(virtualTable:using:) method:
try db.create(virtualTable: "document", using: FTS5()) { t in // t is FTS5TableDefinition
t.column("content")
}

The virtual table tokenizer
try db.create(virtualTable: "document", using: FTS5()) { t in t.tokenizer = .porter() }See https://www.sqlite.org/fts5.html#fts5_table_creation_and_initialization
