Hi Karl, Thanks for the super quick response!
One question - should this boosting occur during index time or at query time? I'm a bit confused as to where should I apply this boost in order to affect the results of a search query. Once again thanks a lot!

It is probably much eaiser for you to just boost the document based on the values you have: http://lucene.apache.org/java/docs/api/org/apache/lucene/document/Document.h tml#setBoost(float) > - I need to make sure only one document per Category is retrieved. > Categories are also implemented as index fields.

Yes, in most cases that would be the way to go. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
