How to write to and read from the same index

I'm using Lucene running on Tomcat to index a large amount of email data and as the indexer runs through the mailbox creating, merging and deleting documents it does lots of searches at the same time to see if the document exists. Actually all my modification operations are done "in batch" every x

Query for a non-value

Hi there, How do I do a query for the value of a field not being equal to something? For example, we all do Query("field:value") but I want to do Query("NOT field:value") to essentially return all the documents that do not have fields with this value? I've tried this but Lucene always returns no

Re: Lucene and Tomcat, too many open files

Guys, thanks for your help yesterday, I solved my problem! I was actually using an IndexSearcher in another thread that I had forgotten all about. Whoever suggested that IndexReader was to blame was right on the money. I now make sure I close my Readers and, bingo, the open files are managed ni

Unnormalized score

Hi, Apparently there is a way of retrieving the unnormalized score from a Hit but I have been unable to track this down. I need to return this value because an external client wants to compile results from multiple queries itself. Any help much appreciated. Cheers, Nick. -

Lucene and Tomcat, too many open files

Hi, What's the best way to manage the number of open files used by Lucene when it's running under Tomcat? I have a indexing application running as a web app and I index a huge number of mail messages (upwards of 4 in some cases). Lucene's merging routine always craps out eventually with the
