Re: how to safely periodically reopen the IndexReader?

Yes, I'm using a solution quite similar to this one. :) But when I read the Lucene 2.3 IndexReader.java code and javadoc, I see they have added a synchronous reference-counter to IndexReader and when it drops to zero, this instance will automatically call doClose() to clean, but the manipulator me

Where can i find the information regarding embedding lucene with database. Thanks http://marceloochoa.blogspot.com/2007/09/running-lucene-inside-your-oracle-jvm.html http://issues.apache.org/jira/browse/LUCENE-434 Cheers Mark

Re: Which file in the lucene package is used to manipulate results..

To add to what Mark is saying, it's very important that watch out for the first N results effect. If you showed a user a random set of documents with crap relevance I'll bet you that a good number will click on the first result (call it user laziness or the Google "I'm feeling lucky" effect :)).

Re: Boost Single Values in Field

You have two options: 1. Boost the term on the query side. The query parser pretty much takes exactly the syntax you use. 2. Use Payloads along with the BoostingTermQuery. Search the archives for info on one or both. -Grant On Feb 20, 2008, at 11:30 AM, JensBurkhardt wrote: Hey, I'm wo

Boost Single Values in Field
