yep, just use a customied similarity that doesn't include a length factor
when computing the norm.
If you are currently using TFIDFSimilarity (or one of it's subclasses)
then the computeNorm method delegates to a lengthNorm method, and you
can override that to return "1" for fields with a cert
Hi Mike,
I'd be happy to, but I have never used JIRA before and I don't entirely
understand what you mean by adding a test case as a patch (academic
programmer here, we are notoriously ignorant of established development
practices :P).
thanks!

Thanks for the reply and information.
I have some doubts regarding the implemenation of lucene54
codec when writing the posting lists using the lucene50 postinglistwriter
while going through the code. What exactly does the finish() method in the
TermsWriter class of the BlockTreeTerms

The posting list is compressed using a specialised technique aimed at
pure numbers. Currently the codec uses a variant of Patched Frame of
Reference coding to perform this compression.
A good survey of such techniques can be found in the good IR books

Hello ,
We are trying to implement better compression techniques in
lucene54 codec of Apache Lucene. Currently there is no such compression for
posting lists in lucene54 codec but LZ4 compression technique is used for
stored fields. Does anyone know why there is no compression technique
