Subject RE: Unable to remove from Lucene index
Date Tue, 05 May 2009 10:02:30 GMT
Please elaborate...

 

Here's a code snippet, as you can see I'm not trying to remove or
requesting to remove anything.

 

//Perform indexing

                  for (Class entityType : entityTypes){

                        //read the data from the database

                        //Scrollable results will avoid loading too many
objects in memory

                        ScrollableResults results =
fullTextSession.createCriteria( entityType )

                        .scroll( ScrollMode.FORWARD_ONLY );

 

                        while( results.next() ) {

                              index++;

                              percentage = (long)((index / total) *
100);

                              fullTextSession.index( results.get(0) );

                              if (index % BATCH_SIZE == 0) {

                                    fullTextSession.clear();

                              }

                        }

                  }

I guess you are trying to remove or requesting to remove null referenced
object.

Hi,

 

I'm new to Lucene, and I'm getting an exception while trying to do a
manual indexing operation on one of my entities.

It works fine for the Product entity, but fails for the ProductInfo
entity (see attached).

 

Versions: 

hibernate-search 3.0.1.GA <http://3.0.1.ga/> 

Lucene 2.3
