Re: require new comment for IndexWriter.mergeFactor

I think the best description of various IndexWriter parameters is in Lucene in Action (sorry if this sounds like a plug, but it's not the intention) in section 2.7.1., page 42 ( http://www.lucenebook.com/search?query=mergeFactor ) mergeFactor controls how often Lucene merges segments while indexin

Re: Is There Other Ports of Nutch?

No! Porting nutch in general makes no sense. Since nutch is not a library as lucene but a complete ready to use application you can download and start. There is a kind of 'webservice' (open search rss) to be able to integrate nutch search results in third party applications. Stefan ... and

Re: Question about scoring normalisation

Hello Ira, I am not sure if I know exactly what pivoted normalisation is. I can tell you what I do, in the meantime I will have a look to your paper and I hope that we can discuss this issue further. I work in personalised searching where a second model - a user model - expresses extra relevance

Best Way To Index Database Using Lucene?

Hi, I use php and mysql. The visitors enters data through the web and the data is stored in the database. I want to make portions of that data to be searchable using Lucene. I am thinking of giving that data to Lucene for indexing at the same time of inputing that same data into the database

Re: Best Way To Index Database Using Lucene?

I forgot to mention that if I use php-java-bridge to use Lucene to index at the same time I input the data into the mysql db, I don't even need to use JDBC. If I index inside the business logic layer which is java, then I will have to use JDBC. --- Victor Lee <[EMAIL PROTECTED]> wrote: > Hi, >

You should check your logs on server side(on tomcat). I am sure some exception is generated over there. --Manoj - Original Message - From: "Gaston" <[EMAIL PROTECTED]> To: Sent: Saturday, November 05, 2005 10:51 PM Subject: lucene and jsp > Hallo, > > I know my topic is a little bit
