Hi All,
I have the following set up: a) Indexed set of docs. b) Ran 1st query and
got tops docs c) Fetched the id's from that and stored in a data structure.
d) Ran 2nd query , got top docs , fetched id's and stored in a data
structure.
Now i have 2 sets of doc ids (set 1) and (set 1).

I have one million records to index, each of which have "Tiltle",
"Desciption" and "Identifier". If take each document and try to index these
fields my program was very slow. So I took 100,000 records and get the value
of these fields, add them to the addDocument() method. Then I use the Index

The issue is solved. Luke was very helpful in debugging, infact it helped to
identify a very basic mistake we were making.

Though there are many, I feel my problem is little different from that and
like to get some advice on this.
Details:
1. Using a machine with RAM 2GB

I have indexed the docs successfully under the directory "LUCENE" under
current directory, which have segments, _1.cfs and deletable.
Now trying to use the following code to search the index but not getting any
HITS. But when I try to read through Reader and get the document with field
mentioned
Hi All,
I have queried and have got a HITS object which is a collection of
documents. I want to find out the centroid of these documents. Centroid =
Top Most 35(for eg)common terms across all the documents in the HITS
object.
Is there any API in Lucene for this?
Thanks in Advance.

If this is not clear please let me know. I have't pasted the latest code
where I have fixed the lock issue as well. If required I can do that.
Thanks everyone for quick turnaround and it really helped me a lot.

There is another approach also but certain issues are there:
try
{
writer.close();
}
finally
{
FSDirectory fs = FSDirectory.getDirectory("./LUCENE",false);
if(IndexReader.isLocked(fs));
{
IndexReader.unlock(fs);
}
}
Thanks a lot again.

IndexWriter takes
time that too when we are appending to the Index file this happens.
So what is the best approach to handle this?
Thanks in Advance.

metadata collected from a website which have a huge collection of documents.
This metadata xml has control characters which causes errors while trying to
