Hi all,
Got stuck at a place and not able to think what should I do.
I have one structure which I have to index. Let say the structure name is
Contract which has a unique Contract_ID. Let say I have 50 contracts which I
have to index.
Now each contract has let say 100 different keys with their va

Would love to see it’s available.

As of 3.2 the necessary changes were put in to safely support indexing nested

I did run it on a 64bit win7 and use Lucene 3.0.3. The result that FSD
outperforms RAM in this case seems to be consistent as I ran a bunch of tests.
My wild guess is that FSD can leverage the MMapDirectory advantage as well as
the three tuning parameters. Just a thought.

Hi,
It depends on the Lucene version, so if the test uses latest Lucene on a
64bit OS, it may use MMapDirectory internally (returned on
FSDirectors.open()) - then its comparing the same with the same - reading
from ram memory :-)
Maybe the difference is also caused by not warming hotspot's compil
This test is very old (from the 1st edition of the book but removed
from the 2nd).
Modern OS's cache newly written files in RAM, and this test doesn't
write very large files (I think?), so the test is really testing an
OS's IO cache vs Lucene's RAM Dir.
That said, I'm not sure why RAMDir would be
Ian,
Thanks a lot for the heads up. I didn't even know those detailed
release notes existed - I just looked on the main release page and
searched a bit through JIRA.
Cheers,

Yes,
You'd need to delete the document and then re-add a newly created document
object. You may use the key and delete the doc using the Term(key, value).

Hi Pranav,
Why would you want to do that in the first place? You could use a separate
field to process whatever it is that you're trying to do.
Also, you can not change the docid (as there's no reasonable reason for
doing so either).
Let me know what is it that you're trying to achieve/target.

Hi Anshum,
Thanks for answering my question. By this I got to know that I cannot update
without deleting my document.
So whenever I am indexing the documents first I need to check whether the
particular key exists in the document or not and if it exists I need to
delete it and add the updated one
Hi all,
Is there any way to change my lucene document no?
Like if I can change my lucene document no's with con_key.
I am a newbie and don't know whether this is a silly question or not.
Please reply.
Thanks
Hii Pranav,
By what you've mentioned, it looks like you want to modify a particular
document (or all docs) by adding a particular field in the document(s). As
of right now, its not possible to modify a document inside a lucene index.
That is due to the way the index is structured. The only way as
