What version of lucene are you using? From Lucene 5.1 you can tell queries to not report scores, which will give you the speedup you require here. Alan Woodward www.flax.co.uk On 30 Jul 2015, at 05:22, 丁儒 wrote: > > > It seems that ConstantScoreQuery use the Weight and Score of the Query i

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 T

Hi, all Currently i'm using lucene. But i don't care the score and weight, i just need the documents meets the query. I tried some way to ignore the score, like rewrite TermQury, disable the TermWeight and TermScore, but there are a lot of queries, and this is incompatible with QueryParser.
