If you are only interested in doc addition sorting, then it should be easy
to reverse the doc orders in each segment, using something like IndexSorter.

Yeah, but IndexSorter is offline. I need an online sorter. The trouble is
as Mike pointed out, the delta encodings are forward only. I do not know of
an available encoding to do this.

I've just created a small web application which you might find useful.
You can see which words are matched by a query word when using different
analyzers (phonetic and stemming analyzers).
These include snowball, kstem and minimal stem (the ones on the right).

Hi,
I use a custom analyzer and tokenizer. The analyzer is very basic and it
merely comprises the method createComponents():
-
@Override
protected TokenStreamComponents createComponents(String fieldName,
Reader reader) {
return new Toke
Disable this warning, your workaround is worse than the warning.

Hi all,
Recently, we are developing a platform with lucene. The ordering rule we
specified is the document with the shortest distance between query terms ranks
the first. But there may be a little different with SpanNearQuery. It returns
all the documents with qualified distance. So I am con
Add &debugQuery=true to your query and look at the "explain" section to see
how the scoring is calculated for each document. Sometimes it is
counter-intuitive and some factors may differ but those differences can be
overwhelmed by other, unrelated factors.

Oops... sorry, I just noticed that you are a Lucene, not Solr, user. Call
the IndexSearcher#explain method to get the explanation and call the
toString method on the explanation to see the readable text.

Great! For my favorite example of "invest", "invests", etc. it shows:
SnowballEnglish:
•investment
•invest
•invests
•investing
•invested
kStem:
•investors
•invest
•investor
•invests
•investing
•invested
minimalStem:invest
•invest
•invests
That highlights the distinctions between these stemmers

Hi Jan,
Basically, DrillDown is a helper class for creating such queries. You're
right that its query() methods create AND, because that's normally the
case, but if you require OR, you could do this:
BooleanQuery res = new BooleanQuery();
for (CategoryPath cp : paths) {
res.add(new
