Time for some standardised index metadata?
OK, thinking out loud... What if we created IntField, subclassing Field. It holds a single int, and you can add it to Document just like any other field. Once added, something inside the index (a "write once" schema) records that this field is an IntField and then it's an error to ever use a different type field by that same name. This field would have int(number)-specific options, with good defaults. So eg one option would turn on Trie* indexing (would default to on). You could set zero padding, etc. (And ShortField, LongField, FloatField, DoubleField, etc.; they could all inherit from NumericField) Couldn't we do this incrementally today? It should be fully back-compatible...
