Ok. So I'm not an expert of the scoring algorithm, but based on tf*idf you can tell that the returned document is more relevant because it has more term frequency.
Using the explain you can see the following: Doc 1 0.643841 = (MATCH) fieldWeight(searchable:fifa in 0), product of: 1.0 = tf(termFreq(searchable:fifa)=1) 1.287682 = idf(docFreq=2) 0.5 = fieldNorm(field=searchable, doc=0) Doc2 0.68289655 = (MATCH) fieldWeight(searchable:fifa in 1), product of: 1.4142135 = tf(termFreq(searchable:fifa)=2) 1.287682 = idf(docFreq=2) 0.375 = fieldNorm(field=searchable, doc=1) On Fri, Apr 25, 2008 at 2:30 PM, Daniel Freudenberger < [EMAIL PROTECTED]> wrote: > I'm using the StandardAnalyzer - hope this answers your question (I'm > quite > new to the lucene thing) > > -----Original Message----- > From: Jonathan Ariel [mailto:[EMAIL PROTECTED] > Sent: Friday, April 25, 2008 6:59 PM > To: java-user@lucene.apache.org > Subject: Re: boosting relevance of certain documents > > How are you analyzing the searchable field? > > On Fri, Apr 25, 2008 at 12:49 PM, Daniel Freudenberger < > [EMAIL PROTECTED]> wrote: > > > Hello, > > > > > > > > I'm using lucene within a new project and I'm not sure about how to > solve > > the following problem: My index consists of the two attributes "id" and > > "searchable".
