Robert Muir updated LUCENE-1260:
--------------------------------
Attachment: LUCENE-1260_defaultsim.patch
Here's a patch for the general case, and it also adds a warning
that you should set your similarity with Similarity.setDefault, especially if
you omit norms.
We can backport this to 3.x
The other cases involve fake norms, which I think we should completely remove
in trunk
with LUCENE-2846, then there is no longer an issue and we can remove the
warning in trunk.
