And naturally Lucene has change a good deal between versions. This is true only if you don't use discovery. If you turn on discovery you can just ignore the "legacy" dspace search system based on lucene. Discovery was available out-of-box in 1.8 for XMLUI (just require some configuration changes). If you use JSPUI you have two routes: - upgrade to dspace 3.x where discovery is available - use or look to the dspace-cris 1.8.2 sources where discovery is present https://github.com/CILEA/DSpace/releases/tag/dspace-cris-1.8.2.1-beta Andrea > End of that road.

Re: [Dspace-tech] Upgrade to Solr
Hello, Some update: After fighting dependencies, especially logging libraries, I discovered that not only SolrJ is using Lucene but DSpace uses it directly in its search.

Re: [Dspace-tech] Upgrade to Solr
Hi Hardy,
We built a new UI outside of DSpace which our Jorum users will be using
for all their search and stats queries. (That is the introduction for
everyone who was not at OR13 in our DSpace API session ;-))
For that UI we built an ES index where the stats is a inner-document to
the item. See below if you are interested otherwise you can safely
ignore the next bit. Indentation is off as well.

We got a script which creates that ES index out of Solr stats and
discovery indexes. But since we need to keep that ES up to date we added
to the statistics package an ElasticSearchLogger.java (intgrated into
UsageStatsEntity.java) and added a new Consumer to
event.dispatcher.default.consumers which gets triggered whenever
something happens to an item.
This all worked very well until we built the ES with our real data and
ES fell over with memory problems -- Footprint of 6GB in memory with a
fairly moderate index. The new version of ES solved the memory problem
but is causing library conflicts. As usual you can't have everything.
That far to the 'tell me more' part. The other question of whether I
would consider contributing - yes, if that stuff is interesting to
anyone else. Building the ES index is one bit but there is nothing
within DSpace which is using it - that part is completely external.
(And I have not forgotten your question for making the sources open to
the Rubi-UI either. We are heading towards the release of it.)
Best regards,
Anja

Re: [Dspace-tech] Upgrade to Solr
Hi Helix, We were using ES 20.6 before - that did not cause a problem. I got the same dependency as you in Maven just with a different version. They just have one 'catch all' jar or ES. At the moment I am considering upgrading Solrj to 3.5 which does not have a dependency on Lucene. That might solve the problem without having to upgrade Solr itself. Thanks a lot.

Re: [Dspace-tech] Upgrade to Solr
Hi Andrea, hi Helix, First of all thank you both for your replies. Your question is a very good one. I entirely agree. Unfortunately I am not aware of a ElasticSearch client library. Before integrating ElasticSearch in our DSpace I have not worked with ES before, meaning I followed the guides (http://www.elasticsearch.org/guide/reference/java-api/) and looking at the Maven repository (http://mvnrepository.com/artifact/org.elasticsearch) I can't see a java client lib either. Looking at Solrj it seems that version 3.3, which DSpace 1.8 is using, is depended on lucene, but Solrj 4.4 is not. (That does not help in its own right - but going in the right direction.) I would very much like to get out of that upgrade, I just can't see how at the moment.

Re: [Dspace-tech] Upgrade to Solr
Hi Anjia, as reported by helix we are in process to upgrade the solr used by DSpace to Solr 4. We have already get a working dspace installation with solr 4.1 many changes are required primary at configuration level. I have a vague memory of issues that I have had trying to use a more recent solr... I will do a try in the next few days and send an update. If no major issues are present we will be happy to update to the last stable solr release. Now a question for you: why the upgrade of elastic search make trouble to dspace and solr? you dspace application should be only dependent from the elastic search client or solrj. Lucene should be hidden by that.

Re: [Dspace-tech] Upgrade to Solr
Also forgot to mention the upgrade to from 3.3->3.5, since you're running DSpace 1.8, not 3. https://jira.duraspace.org/browse/DS-1181 Regards, ~~helix84 Compulsory reading: DSpace Mailing List Etiquette https://wiki.duraspace.org/display/DSPACE/Mailing+List+Etiquette -- Get 100% visibility into Java/.NET code with AppDynamics Lite!

[Dspace-tech] Upgrade to Solr
Hello, We are using DSpace 1.8. We modified the source to use ElasticSearch as well as the build in Solr. After upgrading ElasticSearch to 0.90.3 we are now forced (library conflict with lucene) to update the build in Solr to 4.4.0. Is the version of Solr which comes with DSpace in any way modified to make it work with DSpace? Did anyone attempt an upgrade to Solr 4.4.0 before? Are there any known pit-falls? Any advice appreciated! Best regards, Anja -- Get 100% visibility into Java/.NET code with AppDynamics Lite! It's a free troubleshooting tool designed for production.
