Subject [jira] Commented: (LUCENE-1045) SortField.AUTO doesn't work with long
Date Mon, 26 Nov 2007 20:57:43 GMT


Doug Cutting commented on LUCENE-1045:

> True, it isn't all that useful of an interface.

Perhaps it should be an abstract base class instead of an interface, so that the API can more
easily evolve without breaking user code?  If external implementations are not currently supported,
this might even be a back-compatible change.

I'm attaching a test case by dragon-fly999 at hotmail com that shows the problem and a patch
that seems to fix it.
> The problem is that a long (as used for dates) cannot be parsed as an integer, and the
next step is then to parse it as a float, which works but which is not correct. With the patch
the following parsers are used in this order: int, long, float.
