Hello

I am rebuilding the entire index using the flushToIndexes() approach (Hibernate Search v3.3). I purge the index first, the rebuild the entire content.
This works fine on principle but performance is not great, due to loads of attachments linked to my entities.

Is it possible to perform a partial update somehow re-indexing the entities but skipping certain fields (if not empty)?
On principle the content of the attachment does not change across release of my apps, so I could do without (once they get indexed after the first upload)

Any idea/help?

Thanks in advance
Beppe

Hi Beppe,
no I'm sorry the internal design of Lucene doesn't allow for partial updates of fields: when using Lucene we have to re-insert and re-analyze all input for any small change. That's the cost we have to pay to get such nice query capabilities.

Something you could try is to use the MassIndexer instead, at least it can use multiple threads so if you have more CPUs you can use them all.

What kind of attachments are you linking?
