Hi folks,
I have a requirement where I want to keep adding deltas (incremental
terms) to a particular document in a lucene index, and get these
additional terms indexed to the SAME document in the index. Is there an
easy/smart way to do it without changing much of lucene ? Deleting and

You might want to look at the Carrot2 project
(http://www.carrot2.org/website/xml/index.xml).
It does clustering and has support for Lucene.

You are right. I was unnecessarily transferring all the results from
Hits object to an ArrayList. I don't know why it never struck me but
this was the step that was taking a lot of time; it was staring at me
all the time.
Thanks, it's running much better now.

I am not sure why you are getting all 60k docs at a time. If you use
the Hits object, it caches the top 50 or so, but doesn't retrieve all
the documents at once.
Also, what are the size of your fields and how many fields do you have
per document?
Have you done any profiling to find the bott

Good grouping by domain realized in nutch... Nutch can serve good example of

If you've rewritten a WildcardQuery and get an empty query, that
means that no terms matched the wildcard expression in the index
pointed to by the IndexReader you provided.

Hi,
I am looking for ways to improve the performance of lucene search in our
app. Lucene performance is visibly slow when there are a lot of
documents to be returned (performance almost seems directly proportional
to the number of documents returned by Searcher). However, we show 20
results per pa

all I want to know about IndexWriter.addIndexes() is if there is a way to
