Hi,
Is there a way to remove a token from a document field entry?. For
example, I've got a UnStored field in my index and I want to remove a
token from this field without doing the delete and add document (because
I'm inserting the documents by date and I don't want to loose that sort).

Hi,
I am currently indexing around 6 million text
documents using lucene.
We have a new server arriving in the next few weeks
which the queries will be run on. With the following
stats: Dell 6650 - 4 x Xeon HT CPU's, 16 GB RAM, 36GB
SCSI Ultra160 Hdd. (connected to 1.5TB IDE RAID with

Wow, with 16GB RAM, I would definitely load the index into RAM. You
can use RAMDirectory(Directory) constructor for that.
As for RAMDrives. I have no experience with those, but I have heard
of some people using ramfs under Linux. Ramfs is a memory based
filesystem. Mount it and you have
I have an index with data about images (those data are obtained from database). In
Document among other fields I have one field that I use for sorting. That field could
take 10 different values (1 to 10). I set boost for that field like following:
viewPriority:1^10
viewPriority:2^9
The boost factor is just one part of the relevance equation. It adjusts
the weight of the term for the query. It can still be trumped by other
more relevant parts of the query. Try adjusting the boost to larger
values.
I do have one question. If you know the order of documents to be
retrieved,
I know there is no way to update a document without doing a delete/add.
But I'm asking if this feature is viable to be implemented in an
efficient way.
Thanks

I do have one question. If you know the order of documents to be
retrieved, why use Lucene? Why not just display the results to the user
in your hand picked order?
I need a very fast search engine because I am working with thousends of
images. Lucine is providing me with that.
Does somebody know
Having more RAM does not necessarily mean you can use it in your
process. Keep in mind that a Xeon is a 32 bit x86 architecture, hence
can only physically address 4GB of RAM.
This means that theoretically a process cannot access more than 4GB (all
of them accounted for can add up to 16GB and more
Another way to get the results you want it to store ViewPriority in
the index. Before you return the results to the user, sort the list by
this field outside of lucene.

Hello
I'm building a web application that uses lucene, the problem I'm facing is that only one user may write to the index each time, and I simply can't imagine a way to deal with this. Anyone ever did something like this ? Should I write a non-web app to add documents to the index ?
Thanks
You can have a central component (a singleton for example) that can be
responsible for writes to the index.

There was a recent discussion on the postgres PERFORMENCE mailing list
(check out their archive) about using over 4GM of ram on linux. AFAIR
the gist of it was that while a single process can't use more than 4G,
the kernel can and *will* use the additional memory for caching.
So I'd recommend
