Subject why the score is not 1.0?
Date Thu, 03 Jun 2004 11:21:46 GMT
Dear all,
 
I have another trouble in one of my program using Lucene. I tried to compare the same string
and use the same analyzer to index it. You can see my code as following:
 
-----------------------------------------------------------------------------------------------------------------------------

import org.apache.lucene.analysis.Analyzer;

import org.apache.lucene.analysis.standard.StandardAnalyzer;

import org.apache.lucene.document.Document;

import org.apache.lucene.document.Field;

import org.apache.lucene.index.IndexWriter;

import org.apache.lucene.queryParser.QueryParser;

import org.apache.lucene.search.Hits;

import org.apache.lucene.search.IndexSearcher;

import org.apache.lucene.search.Query;

import org.apache.lucene.search.Searcher;



public class LuceneIndexExample {



private static final String _indexDir ="c://lucene-index-dir";



public static void main(String args[]) throws Exception {



String sss = "All work and no play makes Jack a dull boy";



Analyzer analyzer = new StandardAnalyzer();

boolean flag = true;

IndexWriter writer = new IndexWriter(_indexDir, analyzer, flag);



Document document = new Document();

document.add(Field.Text("champs", sss));

writer.addDocument(document);

writer.close();



Searcher s = new IndexSearcher(_indexDir);

String str = "All work and no play makes Jack a dull boy";

Query q = QueryParser.parse(str, "champs", analyzer);

Hits hits = s.search(q);



try {

for (int i=0; i<=hits.length();i++){

System.out.println("score of "+ i +" = "+hits.score(i));

}

} catch (IndexOutOfBoundsException e){

}

}

}

------------------------------------------------------------------------------------------------------------------
 
I think i should get "1.0" as the score from the hits collection but got "0.30444607" instead.

 
SOMEBODY KNOWS WHY IT'S GONE LIKE THIS? PLEASE HELP! 
 
Thanks before hand.
 
Uddam
