Attachment: LUCENE-3220.patch
Done. Actually, I wanted to implement the norm table in the way you said, but
somehow forgot about it.
Two questions remain on my side:
* the one about discountOverlaps (see above)
* what kind of index-time boosts do people usually use? Too big a boost might
cause problems if we just divide the length with it. Maybe we should take the
logarithm or sth like that?

Added norm decoding table to EasySimilarity, and removed sumTotalFreq. Sorry I
could only upload this patch now but I didn't have time to work on Lucene the
last week.
As I see, all the problems you mentioned have been corrected, so maybe we can
go on with the review?

EasySimilarity now computes norms in the same way as DefaultSimilarity.
Actually not exactly the same way, as I have not yet added the discountOverlaps
property. I think it would be a good idea for EasySimilarity as well (it is for
phrases, right), what do you reckon?
I also wrote a quick test to see which norm (length directly or 1/sqrt) is
closer to the original value and it seems that the direct one is usually much
closer (RMSE is 0.09689688608375747 vs 0.23787634482532286). Of course, I know
it is much more important that the new Similarities can use existing indices.

Attachment: LUCENE-3220.patch
Fixed two of the issues you mentioned:
* Apache license header added to all files in the similarities package;
* cleaned up the constructor of DFRSimilarity and added a few new ones.
I have not yet moved the NoNormalization and NoAfterEffect classes to their own
files, because I feel a bit uncomfortable about the naming, since it's
different from that of the other classes, e.g. NormalizationH2 vs
NoNormalization.

David Mark Nemeskey updated LUCENE-3220:
Attachment: LUCENE-3220.patch
Implementation of the DFR framework added. Lots of nocommits, though. I things
to think about:
* lots of (float) conversions. Maybe the inner API (BasicModel, etc.) could
use doubles? According to my experience, double is faster anyway, at least on
64bit architectures
* I am not overly happy about the naming scheme, i.e. BasicModelBE, etc. Maybe
we should do it the same way as in Terrier, with a basicmodel package and class
names like BE?
* A regular SimilarityProvider implementation won't play well with
DFRSimilarity, in case the user wants to use several different setups.
Actually, this is a problem for all similarities that have parameters (e.g.
BM25 with b and k).
Also, I think we need that NormConverter we talked earlier on irc, so that the
Similarities can run on any index.
