Subject RE: NumericRangeQuery "static" constructors
Date Wed, 23 Sep 2009 08:34:29 GMT
I forgot to mention, I have a task for 3.0:
https://issues.apache.org/jira/browse/LUCENE-1857

This will add more type safety and then maybe the ctors can be made public
again and the static methods be deprecated/removed. Same for NumericField
and NumericTokenStream. I will do this after commiting the AttributeSource
generics together and many other generics that are important for a clear
(public) Lucene API.
