Indexing with lucene/nutch on top of/instead of DB indexing for: 1) relativity scoring 2) alias searching (i.e. a large amount of aliases, like first names) 3) highlighting 4) cross-datasource searching (multi DB, DB + XML files, etc).
As for best approach to externally index, I do not have any direct pointers. I would recommend looking at an ETL tool that can be extended for this purpose (I've started writing a plugin for Pentaho, but got pulled off and haven't finished it -- and that was for Solr, not lucene/nutch). -D > -----Original Message----- > From: Duan, Nick [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 04, 2008 1:33 PM > To: java-user@lucene.apache.org > Subject: Why indexing database is necessary?
