Thanks Otis. All the documents were written in a using the same
IndexWriter, without ever closing it. Is this what could be responsible for
the documents not being in the segmens file, or is this bad practice? Maybe
I should use a writer for a batch of documents (1000 or so maybe?), and then
Hello,
I would like to figure out if it is possible to write a java applet
able to search with lucene through an HTML documentation WITHOUT
having a webserver installed on the system and on multiple platforms.
So I have a set of static offline HTML files forming a software

Hi Paulo,
The main problem is that Lucene needs to store its index on a disk which under
normal circumstances an applet may not read. The applet operates in a sandbox,
which only allows "safe" operations. Reading and writing to disk is not
allowed. An applet can only get resources from the host
Wouldn't this be a good case for the JarDirectory implementation
somebody asked for?
The index could then be statically written in a jar file downloaded
with the applet (the original mail refers to static offline HTML
files).
It could even be a great idea for improving the Maven site-plugin :-)

Hi,
When StandardAnalyzer is used to index documents, arent the terms,
amongst other things, lower cased and stored that ways in the index?
I have a index field that I index like this:
ramWriter = new IndexWriter(ramDir, standardAnalyzer, true);

Hello,
Not yet an expert in the field, but as I've understood the thing the
terms are indexed as you specify them (through the filters) but the
contents are stored depending on whether you want it or not
(Filed.UnStored(), which happens to be on its way to get deprecated).
So maybe you search the
lets say i do this while indexing:
doc.add(Field.Text("categoryNames", categoryNames));

I do this:

Hi Steve,
If I understand you right, I could use something like the Keyword
analyzer to tokenize the entire stream as a single token and store that
in the index. I could definitely the keyword analyzer while indexing
this particular field "categoryNames".
Now my questions is on how to search
Hi,
Just realized that the various fields I have are part of the same

After indexing is done, you can copy the index files and merge them to
one large index. Or you can maintain several small indexes and search
across indexes.

I think I answered that question just the other day privately...
No, there is nothing in Lucene to help you with CPU utilization.
However, if you are running this on a UNIX box of some kind, you can (re)nice
the process and thus lower its priority, giving other processes more time with
the CP
No, using the same IndexWriter is the way to go. If you want things to be
written to disk more frequently, lower the maxBufferedDocs setting. Go down to
1, if you want. You'll use less memory (RAM), Documents will be written to
disk without getting buffered in RAM, but the indexing process wi

Hi
I'm using Lucene in a web application. Every time a new object is added to
the system the index will be updated. May there be any problems, if two
objects were created at the same moment? I know Lucene has some locking
mechanism.
Thx

We're going to run into this issue when dealing with some of our larger
customers.
What we plan on doing is to separate our indexers in to separate cpus, and then
throttle them by using sleep(100) or some other number to be determined in
testing. We also plan on doing this over 2 weekends, sin
Hi Klaus,
If you use a single instance of IndexWriter, you can call addDocument(...) on
it without synchronizing (things are thread safe inside the call). If you are
opening/closing IndexWriters yourself, then you have to make sure you have only
1 IndexWriter open at a time.
If you have Lucene
