Hi Shay, As I'm creating my own Spanish analyzer, I'd like to know where I can find information about which version of Lucene ships with which version of ES. For instance, I just built the latest master from Git to get the new 'analyzeWildcard()' functionality and I saw within your code that you make references to Lucene 3.1, whilst I'm working with 3.0.3. Thanks. ---

Hi, ES is now running on top of Lucene 3.0.3 ( [https://github.com/elasticsearch/elasticsearch/blob/master/modules/elasticsearch/build.gradle#L40](https://github.com/elasticsearch/elasticsearch/blob/master/modules/elasticsearch/build.gradle#L40)), you can also check release notes for each version to find out if it upgrades Lucene library. For example ES 0.9.0 switched to Lucene 3.0.2 ( [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/download/2010/07/26/0.9.0.html)) and ES 0.13.1 switched to Lucene 3.0.3 ( [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/download/2010/12/03/0.13.1.html)) Once Lucene 3.1 stable is released and tested with ES then I think Shay will integrate it as soon as possible. You can now find some references to Lucene 3.1 in code comments in some parts in ES now because some Lucene analyzers stuff was back ported from Lucene trunk to enable functionality that is not available in Lucene 3.0.3 (but I believe references to 3.1 are more like a hints for ES developers to keep in mind that they can drop or refactor some classes once switching to 3.1) Regards, Lukas On Fri, Mar 18, 2011 at 10:29 AM, Enrique Medina Montenegro \< [e.medina.m@gmail.com](mailto:e.medina.m@gmail.com)\> wrote: > Hi Shay, > > As I'm creating my own Spanish analyzer, I'd like to know where I can find > information about which version of Lucene ships with which version of ES. > > For instance, I just built the latest master from Git to get the new > 'analyzeWildcard()' functionality and I saw within your code that you make > references to Lucene 3.1, whilst I'm working with 3.0.3. > > Thanks. ---

Thanks a lot. My concern was about the fact that I'm using now the very latest code from master, so there are no available "release notes" yet, as obvious.

Hi, there are some release notes for master here > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. Though not always up to date you can also check closed issues on GitHub (switching to new Lucene 3.1 would certainly have a ticket as it will be a significant update and code refactoring). Note: Personally, I think that Lucene 3.1 will probably not be integrated into 0.16.0 (current master) because it will be a big change so having an easy option for people to switch to ES that is using previous Lucene version will be useful. But do not take me for granted on this.
