It's possible to change Lucene version?.

[sidi]

I've put another post in Webservices but  had no answer. I'm starting to have performance problems as content is increasing. I've made a rebuild of lucene index and got better but still under espected ratio for inserting nodes. Lucene version that comes with  Alfresco community 2.1 is 2.1 if I substitute the .jar files of lucene for 2.3.2 will performance improve?.
Will be compatible and everything works? Should I make another reindex?.
I hope someone helps with this and if could also answer my questions in the Webservices foro I will really apreciate.
Thanks in advance.

Hi

We will upgrade at some point soon. You are welcone to try - but the risk is yours.
You can always revert back and rebuild the index.
