I see, thank you! This explains a lot. Jiri -----Original Message----- From: Michael McCandless [mailto:luc...@mikemccandless.com] Sent: Friday, August 06, 2010 12:47 PM To: java-user@lucene.apache.org Subject: Re: Constant score queries
The score will be 1.0 even if the boost isn't, when you use ConstantScore*Query as the sole top-level query. The boost only impacts how much weight is associated with this query's matches when it's a sub-query mixed in with other sub-queries. EG if you make a BooleanQuery, and add ConstantScoreQuery as a SHOULD clause, and then add something else, eg TermQuery, then if you change the boost of the ConstantScoreQuery you should see that impact which docs/scores are returned.
