Subject RE: Null pointer error when searching with DateFilter
Date Thu, 11 Oct 2001 15:37:52 GMT
Kind words indeed!  Thanks.  :)

I've checked in now, so please check it out and verify the fix for yourself.

(By the way, another way to address a date range selection is with the
RangeQuery I added a while back.  You can include in your main query and in
many circumstances it may be faster than using a Filter.)
