Subject Re: Modify solr score

Since we report the score, we think there will be some relation between them.
As far as we know scoring (and then ranking) are calculated based on tf-idf.

What we want to do is to make a qualitative ranking, it means, according to
one topic we will tag documents as "very related", "fairly related" or "poor
related". So, we select some documents completely unrelated to a topic.

On a very related document we found a ratio of ~2% of words that reports
~0.85 of score (what we think is related to ranking). On a test document we
found a ratio of less than 0.01% and the score is heigher than the first
one. What we expect is that documents not related (those ones with less
ratio) report lower scores so we can then use them as minimum and create the
scale.

We came with multiply (of affect in some way) the default rank solr provide
us with the ratio of documents so unrelated documents will be penalized
while those with higher ratio values will be overrated.

Greetings, and thanks for your help.
