Are you creating new IndexSearchers or IndexReaders on each search? Caching
your IndexSearchers has a dramatic effect on speed.

The problem could be you're writing to an index with multiple processes. This
can happen if you're using a shared file system (NFS?). We saw this problem
when we had two IndexWriters getting access to a single index at the same time.
Usually if you're working on a single machine the file
Sorry if this is the wrong forum but I wondered what's happened to 'Lucene In

a 'hard to find' item and are now quoting a 4-6 week delivery time and tacking
on a rare book charge. Amazon.com are quoting shipping
I have a delete script
IndexSearcher searcher = new IndexSearcher(reader);
Hits hits = searcher.search(query);
log.info(there are + hits.length() + hits);
for (int i = 0; i hits.length(); i++) {
log.info(hits.length() + + i + + hits.id(i));
reader.delete(hits.id(i));

Would it be cheeky to ask you to post the docs to the group? It would be interesting
to read how you've tackled this.

Can lucene be able to search word documents? if so please give me information about it

Hi Santosh,
Lucene doesn't search pdfs per se. To make anything searchable you have to first
extract the content and then put it in lucene in a form it understands (i.e document
objects). So in order to search your pdfs you first need to extract the info from the
PDFs using something like

Doesn't en UK as a phrase query work?
You're probably indexing it as a text field so it's being tokenised.

There is no problem with updating and searching simultaneously. Two threads updating
simultaneously on the same index on NFS can be a problem, as the locking does not work
reliably. Have a look through the archives for NFS, there are some solutions
scattered about.

You say the content is indexed, is it stored? If note, index the content of the
document, but don't store it.
eg
doc.add(Field.UnStored(content, content));

What is it good
Why don't you take a look at luke. That way you can play with the index you built and
work from there. If you're looking to replicate something like Luke, I'd get studying
now ;).

In my system indices are created and updated by multiple threads. I need to check if
an index exists to decide whether to pass true or false to the IndexWriter constructor.
new IndexWriter(FSDirectory, Analyzer, boolean);
The problem arises when two threads attempt to create the same index
Does this mean if you can insure that only one IndexWriter and/or IndexReader(Doing
deletion) are never open at the same time (eg using database instead of lucene's
locking), there will be no problem with removing locking? If you do not use an
IndexReader to do deletion can you open and close
I would advise you to use the excellent articles listed here.

Some good examples and by the end of it you should have a good understanding of the
