Re: Relevance's scores on TopFieldCollector/FieldComparator

In our use-case we are not using filterCache and documentCache in our solrconfig.xml because we are interested in the maximum random repetitions. That's the reason to don't use caches.

Maybe that was the reason to get 0s in the ScoreCachingWrapper.

It's odd that this was necessary.

The ScoreCachingWrapperScorer simply wraps (and caches) the result
from calling score(), per hit, so that if score() is called more than
once we don't have to re-compute it. I don't understand why you were
always seeing 0 score come back from it.
