Looking for Lucene index version

When I use Luke V3.3.0, it tells me that the Lucene index that I am opening is:

• Index version: 13172b074a7
• Index format: -11 (Lucene 3.1)

I am using Solr 3.3, I removed previously my folder /var/data/solr/myrepository before indexing. I would expect the version to be Lucene 3.3. There is no index change between Lucene 3.1 and Lucene 3.3 开发者_如何学JAVA? At the end of the day, I just want to make sure that my index was created using Lucene 3.3. Any easy way to get the Lucene index version is what I am looking for.

Also field collapsing works so, if there's an index change, my index version is correct. I don't see this info either from the Solr admin page.

Thank you.

You can see the Lucene version being used by clicking on the [Info] link on the top of the Solr Admin page. It will take you to http://<yourserver:port>/<instancename>/admin/registry.jsp

The Solr and Lucene Specification and Implementation versions are listed in the top section of the Solr Info page.

I am using Solr 3.3 and this is what I see...
