It seems that ConstantScoreQuery use the Weight and Score of the Query it wrapperd, like TermWeight and TermScorer , so it can't speed up the search, because the weight and score is still calculated. Maybe i make it wrong, but i did some test, the search time of ‘ new ConstantScoreQuery(new TermQuery)’ is the same as 'new TermQuery'.
