RE: java.io.IOException: Lock obtain timed out
I notice in your "catch" clause you always set the
writer to be true... (i.e. new IndexWriter(INDEX_DIR,
analyzer, true).
If I am not mistaken reading the docs, this overwrites
the entire index, no? That is why I was setting that
variable to false when doing an incremental update.
When I reindex all documents, I have had no problem.

Re: java.io.IOException: Lock obtain timed out
Otis, I only put the unlock call in because I had the error in the first place. Removing it, the IOException still occurs, when trying to instantiate the IndexWriter.

java.io.IOException: Lock obtain timed out
I am using Lucene 1.3 final and am having an error that I can't seem to shake. Basically, I am updating a Document in the index incrementally by calling an IndexReader to remove the document. This works. Then, I close the IndexReader with the following code: reader.unlock(reader.directory()); reader.close(); I put the first of the two lines in to try to force the lock to disable. According to the logging, this code is being called and the IndexReader is being closed. However, then I open a writer to add the document, I get the following. java.io.IOException: Lock obtain timed out at org.apache.lucene.store.Lock.obtain(Lock.java:97) at org.apache.lucene.index.IndexWriter.(IndexWriter.java:173) at ... I open the writer by calling: return new IndexWriter(INDEX_DIR, analyzer, false); where analyzer=new StandardAnalyzer(); I get the reader by calling: IndexReader reader=IndexReader.open(INDEX_DIR); Thanks for any help, Gabe __ Do you Yahoo!?

Re: Ordering by a field value
Thanks Otis. What will the names of the relevant files be and will I be able to use 1.3 final still (simply integrating the contributions into my own code) or would I have to go with the latest code from CVS?

Ordering by a field value
Hi, I was wondering whether it was possible to sort search results by the order of the String value of a stored or unstored field. How would one implement this? Thanks, Gabe __ Do you Yahoo!? Yahoo!

arrays of values in a field
If I have a group of documents and I want to filter on a category, it is fairly straightforward. I just create a Field that contains the category and filter on it. However, what if I want the field "category" to have multiple possible values? Is there a known best way to filter on that? I imagine it is possible to "hack" it by, say, creating a field with value: |category1|category2|category3| etc. And then query "|category1|" I was wondering if there was a better way.
