Yes it helps me understanding, thank u. I make a BooleanQuery with the input of the user and include in the query title:keywordofuser headlines:keywordofuser content:keywordofuser I tried to Boost field title, then if keyword appear in the title, score grows like I want to, but if keyword occurs in content or headlines score decrease more than before ... I would like to have a score independent for each query in the BooleanQuery, sounds basic but I just can't achieve this. Is this also possible to change ? Thank u.
>>Soren The score is not one (0.3764683). If it should to be one you can normalize the score. What do u mean by normalizing the score and how ? -----Original Message----- From: Chris Hostetter [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 30, 2007 12:00 AM To: java-user@lucene.apache.org Subject: Re: Score ***** This message comes from the Internet Network ***** Note also that the scores in an Explanation are the "raw" scores ... if you use Hits, the scores are "partially normalized" meaning that if the highest scoring document has a score greater then 1, all scores are devided by the highest score. : Date: Mon, 29 Jan 2007 21:52:58 +0100 : From: Soeren Pekrul <[EMAIL PROTECTED]> : Reply-To: java-user@lucene.apache.org : To: java-user@lucene.apache.org : Subject: Re: Score : : DECAFFMEYER MATHIEU wrote: : > : > Both are the same document but in different indexes, : > the only difference is that the second idnex has more document than the : > first one, the first one contains only that page. : > I would like to have the same score as in the second index, : : Simple speaking, the score depends of the query, the matched document : and the index.
