Re: Ordening documents
Yes, this is correct.

then this means that documents with equal score are returned in the order in

have a look at the source of the lessThan method in
org.java.lucene.search.HitQueue:
protected final boolean lessThan(Object a, Object b) {
ScoreDoc hitA = (ScoreDoc)a;
ScoreDoc hitB = (ScoreDoc)b;
if (hitA.score == hitB.score)
return hitA.doc > hitB.doc;
else
return hitA.score < hitB.score;
}
sorting is done by this method.

RE: Ordening documents
William, The order of the results are going to be based on how well they match the query (i.e. weighted by relevancy). So although all of those values contain the term "Palm", I would assume you would get the shorter entries (i.e. 1 & 3) before the longer ones (2) as they have a higher percentage of "palmness". Same goes for the second query (it is a better match for 1, than 2). If you want the documents to come back in their document order, you would need to sort the results yourself. -Mike At 02:33 PM 1/16/2004, you wrote: Hi Folks, To the order of the result What really matters is ONLY the order in which the information is stored in the index ?
