Hi, I try to read the source code of the lucene. But i only find in the TermScorer.java where the tf/idf measure is really implemented. I guess that whether the Queryparser class will convert each word into a termquery first. Then, queries such as the the Booleanquery are built.
The source code of the Queryparser.java is hard to read. .... regards jiang xing On 2/5/06, Klaus <[EMAIL PROTECTED]> wrote: > > Hi, > > you have to write your own similarity object and pass it to your analyzer. > > > http://lucene.apache.org/java/docs/api/org/apache/lucene/search/Similarity.h > tml > > Cheers, > > Klaus > -----Ursprüngliche Nachricht----- > Von: xing jiang [mailto:[EMAIL PROTECTED] > Gesendet: Sonntag, 5.
