Lucene Upgrade from 2.9.x to 4.7.x
Hello, I'm looking for some documents/information on upgrade from Lucene 2.9.x to 4.7.2. This is the first time I'm doing a upgrade. Can someone point me to some help in this? Is there a documentation on "what has changed" from 2.9.x to 4.7.2? Thanks, Suresh

RE: Lucene Upgrade from 2.9.x to 4.7.x
I was trying the Demo application from 4.7.2 on an index created by 2.9.1. I get a org.apache.lucene.index.IndexFormatTooOldException exception. I tried the upgrader tool. Same exception again. Is there an upgrader tool that can work with a 2.9.1 tool? Or Do I have to build one? Any guidelines would helpful Thanks, Suresh -Original Message- From: Buddhavarapu, Suresh [mailto:suresh.buddhavar...@emc.com] Sent: Friday, May 30, 2014 1:13 PM To: java-user@lucene.apache.org Subject: RE: Lucene Upgrade from 2.9.x to 4.7.x Thanks Xiaolong.

After this, your index is in Lucene 3.6 format, which can be read with Lucene 4.

IndexReader.document method - Why is this made final?
Hi, I'm working on an upgrade of project of Lucene from 2.9.3 to 4.10. We have a need to implement the IndexReader interfact to create an abstraction over two disparate indexes. First, I found that Indexreader can no longer be extended. Instead I chose to extend the CopositeReader abstract class. Also, I find the the IndexReader.document method has been declared final. Is there any reason why this has been made final? I wanted to understand the thinking behind this change before I think of another approach. I also find the StoredDocument is not documented yet. I only see this in the source code. Thanks, Suresh
Effectiveness MMapDirectory on NFS Mounted indexes
Hi, I'm using Lucene 2.9.3 on a 64 bit machine. Many a times we are observing that the systems gets into to thrashing mode during merges. We are experimenting with using MMapDirectory. Our index is stored on NFS/CIFS mounted file shares. My question, is this MMapDirectory useful in such scenarios, I mean for indexes on a network file share? Any experiences or thoughts on this? I cannot really migrate to latest lucene as of now. Thanks, Suresh
