FAQ
My personal thoughts/preferences/suggestions for Luke:

1. Need a clean Luke Java library – heavily unit-tested. As integrated with Lucene as possible.
2. A simple command line interface – always useful.
3. A Solr plugin handler – based on #1. Good for apps as well as Admin UI. Nice to be able to curl a request to look at a specific doc, for example.
4. GUI fully integrated with the new Solr Web Admin UI. A separate UI... sucks.
5. Any additional, un-untegrated GUI is icing on the cake and not really desirable for Solr. May be great for Elasticsearch and other Lucene-based apps, but Solr should be the #1 priority – after #1 and #2 above.

Subject: Re: Request for Mentor for LUCENE-2562 : Make Luke a Lucene/Solr Module

Hello guys,

Indeed, the GWT port is work in progress and far from done. The driving factor here was to be able to later integrate luke into the solr admin as well as have the standalone webapp for non-solr users.

There is (was?) a luke stats handler in the solr ui, that printed some stats on the index. That could be substituted with the GWT app.


The code isn't yet ready to see the light. So if it makes more sense for Ajay to work on the existing jira with the Apache Pivot implementation, I would say go ahead.


In the current port effort (the aforementioned github's fork) the UI is the original one, developed by Andrzej. Beside the UI rework there is plenty things to port / verify (like e.g. Hadoop plugin) against the latest lucene versions.

See the readme.md: https://github.com/dmitrykey/luke



Whichever way's taken, hopefully we end up having stable releases of luke :)

     Shawn and Andrzej,

     Thanks for answering my questions. I've looked over the code done by
     Dmitry and I'll look into what I can do to help with the UI porting in
     future.

     I was actually thinking of doing this JIRA as a project by myself with
     some assistance from the community after getting a mentor for the ASF
     ICFOSS program, which I haven't found yet. It would be great if I could
     get one of you guys as a mentor.

     As the UI work has been mostly done by others like Dmitry Kan, I don't
     think I need to work on that majorly for now.



   It's far from done - he just started the process.



     What other work is there to be done that I can do as a project? Any new
     features or improvements?

     Regards,
     Ajay

                 One more question : What version of Lucene does Luke
                 currently support
                 right now? I saw a comment on the issue page that it doesn't
                 support the
                 Lucene 4.1 and 4.2 trunk.


             The official Luke project only has versions up through 4.0.0-ALPHA.

             http://code.google.com/p/luke/

             There is a forked project that has produced Luke for newer
             Lucene versions.


             https://java.net/projects/__opengrok/downloads

             <https://java.net/projects/opengrok/downloads>

             I can't seem to locate any information about how they have
             licensed the
             newer versions, and I'm not really sure where the source code is
             living.

             Regarding a question you asked earlier, Luke is a standalone
             program.
             It does include Lucene classes in the "lukeall" version of the
             executable jar.

             Luke may have some uses as a library, but I think that most
             people run
             it separately. There is partial Luke functionality embedded in
             the Solr
             admin UI, but I don't know whether that is something cooked up
             by Solr
             devs or if it shares actual code with Luke.


         Ajay,

         Luke is a standalone GUI application, not a library. It uses a
         custom version of Thinlet GUI toolkit, which is no longer
         maintained, and it's LGPL licensed, so Luke can't be contributed to
         the Lucene project as is.

         Recently several people expressed interest in porting Luke to some
         other GUI toolkit that is Apache-friendly. See the discussion here:


         http://groups.google.com/d/__msg/luke-discuss/S_Whwg2jwmA/__9JgqKIe5aiwJ

         <http://groups.google.com/d/msg/luke-discuss/S_Whwg2jwmA/9JgqKIe5aiwJ>

         In particular, there's a fork by Dmitry Kan - he plans to integrate
         other patches and forks, and to port Luke from Thinlet to GWT and
         sync it with the latest version of Lucene. I think you should
         coordinate your efforts with him and other contributors that work on
         that code base. This fork is Apache-licensed and the long-term plan
         is to contribute it back to Lucene once the porting is done.

         The Pivot-based port of Luke that is in the Lucene sandbox is in an
         early stage. I'm not sure Mark Miller has time to work on it due to
         his involvement in SolrCloud development.

         The Luke handler in Solr is a completely different code base, and it
         shares only the name with the Luke application.
