Thanks Jeroen and Upayavira!
I read the warning about losing the ability to use index time boosts when I
disable length normalization. And we actually use it; at least if it means
having a boost field in the index and doing queries like this:
"{!boost b=boost}( series:RCWP^10 OR otherFileds:queries^2)"
Is there a way to omitNorms and still be able to use {!boost b=boost} ?
Thanks,
Alexander
