MultiReader docid reliability
Hi, from the javadocs: For efficiency, in this API documents are often referred to via document numbers, non-negative integers which each name a unique document in the index. These document numbers are ephemeral -- they may change as documents are added to and deleted from an index. Clients should thus not rely on a given document having the same number between sessions. What does it mean in this context sessions? Are search sessions? 1) If I have an index that does not change (no deletes or updates) and I'm keeping the MultiReader open, can the docid change executing more times the same search on that reader? 2) Opening the same set of indexes in a MultiReader on different machines will assign different docids to the same document at runtime or the algorithm to calculate such docids in some way can guarantee that static indexes will have the same docids in different machines (than separated JVMs)? nicola. -- Nicola Buso nb...@ebi.ac.uk EMBL-EBI - To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
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
The migration guide that came out with 4.0 is probably the best place to start. http://lucene.apache.org/core/4_8_1/MIGRATE.html is from the current release but probably hasn't changed since 4.0. There's also the changes file with every release. And if you browse the list archives I expect you'll find similar questions and answers. -- Ian.

Re: Lucene Upgrade from 2.9.x to 4.7.x
I just upgrade Lucene from 2.0.0 to 4.6.1, here is a list of collections that I was using during the upgrade: 1. Lucene 2.0 API http://www.lhelper.org/dev/lucene-2.0.0/docs/api/index.html 2. Lucene 4.7.2 Core API http://lucene.apache.org/core/4_7_2/core/index.html 3. Lucene 4.7.2 Analyzers-Comon API http://lucene.apache.org/core/4_7_2/analyzers-common/index.html?overview-s ummary.html 4. Lucene 4.7.2 QueryParser API http://lucene.apache.org/core/4_7_2/queryparser/index.html 5. Lucene Change Log http://lucene.apache.org/core/4_7_2/changes/Changes.html 6. Apache Lucene Migration Guide http://lucene.apache.org/core/4_7_2/MIGRATE.html I would like to say number 5 is also very helpful.

I am curious what type of time-frame it took you to do the upgrade, including acceptable unit and QA tesing? -Original Message- From: Xiaolong Zheng [mailto:xiaolong.zh...@mathworks.com] Sent: Thursday, May 29, 2014 9:14 AM To: java-user@lucene.apache.org Subject: Re: Lucene Upgrade from 2.9.x to 4.7.x I just upgrade Lucene from 2.0.0 to 4.6.1, here is a list of collections that I was using during the upgrade: 1.
