Currently I've take the score that I get from Solr, and divide it by the maxScore, and multiply it by 100 to get the percentage. All these are done on the coding for the UI. The user will only see the percentage and will not know anything about the score. Since the score by itself is meaningless, so I don't think I should display that score of like 1.7 or 0.2 on the UI, which could further confuse the user and raise alot more questions.
