Re: When are deletions permanent?

When you close the IndexReader you know the delete is commited to disk. I believe calling the commit method will also guarantee that all changes are written to disk. --- Lucene Users List lucene-user@jakarta.apache.org wrote: Hi everyone, I need to update a document in Lucene. I

Re: Optimize not deleting all files

Yes, I believe my problem is related to open IndexReaders. The issues is that we can't shut down our live search application while we wait for a 10 minute optimization. Search is a major part of our application and removing the feature would significantly affect our end users (even though we run

Optimize not deleting all files

Hi, When I run an optimize in our production environment, old index are left in the directory and are not deleted. My understanding is that an optimize will create new index files and all existing index files should be deleted. Is this correct? We are running Lucene 1.4.2 on Windows.

Windows Bug?

Hi, My understanding is that I can have an IndexReader open for searching (as long as it doesn't delete) while an IndexWriter is updating the index. I wrote a simple test app to prove this and it works great on Mac OS X, Java 1.4.2 and Lucene 1.4.2. It fails on Windows XP, Java 1.4.2 and

Re: Locks and Readers and Writers

Ok, I simplified my test case a little... I removed the UNC share which is a remote file share that Windows supports. I have two processes running on the same Windows XP machine. 1) The first process uses an IndexWriter to writes to the index and then closes the IndexWriter. 2) The first

Locks and Readers and Writers

Hi, I'm getting: java.io.IOException: Lock obtain timed out I have a writer service that opens the index to delete and add docs. I have a reader service that opens the index for searching only. This error occurs when the reader service opens the index (this takes about 500ms).

IndexReader / IndexSearcher

I'm opening a new IndexReader for every search request which obviously isn't the best option. If I open a reader can I use the same searcher for multiple requests that are happening simultaneously? If I call close on the searcher will it close for all the instances?
