I _think_ Lucene 2.1 (or is it trunk?, I lose track) has the ability to
delete all documents containing a term.
Actually it's been in IndexReader for longer than I can remember. We're
still on 1.4.3 and it's in there.
(Only difference in 2.1 is that it's now on IndexWriter as well.)

There are (at least) two ways to generate a BitSet which can be used for
filtering.
Filter.bits()
BitSet bits = new BitSet(reader.maxDoc());
TermDocs td = reader.termDocs(new Term("field", "text");
while (td.next())
{
bits.set(td.doc());
}
return bits;

i'm not expert on this kind of thing, but since CSIndexInput only reads
from a portion of another IndexInput, closing base seems like a bad idea

Hi All,
I have a question regarding the close() CSIndexInput class, why there is

If I analyze the memory dump of our server I can see lot of object of

Hi Ruchika,
Are there are any quote characters in your index (may the Luke be with
you[1])? If not, you could just remove all quotes from your query
(except the surrounding ones indicating phrase matching, of course), and
things will work, as you have indicated.
Which version of Lucene are you u

As of Lucene 2.1 you can make optimal use of RAM by monitoring
IndexWriter.ramSizeInBytes() and calling IndexWriter.flush() when memory is
tight.
This avoids the issue of trying to estimate a value for maxBufferedDocs which
you think can fit into RAM.
Cheers

I think you can try
MergeFactor =1000
MaxMergeDocs=2147483647
MaxBufferedDocs=1000

I am not sure if I can help you a lot but you can check how Nutch does this

or

You should also check Highliter API (
