1) questions about using Lucene are best sent to the java-user list ... it is for people asking questions about "using" the java lucene library (java-dev is for quesions about "developing" the java lucene library) ... you are more likley to get answers to questions faster on the java-user list.
2) calling the idf method does not modify the Similarity object ... the idf method is what gets called during scoring. if you wnat to change the idf method, you need to subclass DefaultSimilarity, override the idf method, and then pass an instance of your subclass to searcher.setSimilarity. : Date: Fri, 2 Mar 2007 04:23:49 -0800 (PST) : From: jreeman <[EMAIL PROTECTED]> : Reply-To: java-dev@lucene.apache.org : To: java-dev@lucene.apache.org : Subject: Re: [jira] Question about hits scores : : : I have been overwriting the Similarity class of the searcher like this : : : DefaultSimilarity similarity = new DefaultSimilarity(); : similarity.idf(0, 1); // idf is set to 1 whithis line of code : searcher.setSimilarity(similarity); : hits=searcher.search(l_query); : : But it does not modify the hit score. : : Do you have any suggestions ? : : jreeman wrote: : > : > Ok the score depends on the frequence of the hit for each metadata value. : > : > My question is now how to make the score independant from the frequency of : > a result ? : > : > : > : > jreeman wrote: : >> : >> Hello, : >> : >> here is the query I am sending to lucene : : >> : >> +(document_type:type0one +document_type:type0twenty0one) +state:live0 : >> : >> document_type and state are meta-datas. 0 is used as a separator in : >> "type0one " and "type0twenty0one". : >> : >> I was thinking that the hits scores would be all set to 100% but it is : >> not the case : : >> : >> I have this score : : >> : >> 1 hit typetype0one, score 100% : >> 1 hit type0twenty0one, score 80% : >> 1 hit type0twenty0one, score 80% : >> : >> I am using a standart analyzer with no stop words. : >> : >> I don't understand why I don't have all hits with 100% for score. : >> : >> Do you have some explanation ? : >> : >> Thanks in advance. : >> : > : > : : -- : View this message in context: http://www.nabble.com/Question-about-hits-scores-tf3332761.html#a9268663 : Sent from the Lucene - Java Developer mailing list archive at Nabble.com. : : : --------------------------------------------------------------------- : To unsubscribe, e-mail: [EMAIL PROTECTED] : For additional commands, e-mail: [EMAIL PROTECTED] : -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
