This is the default URL for Solr. If you changed it, you can find it in search.server in [dspace]/config/modules/discovery.cfg (DSpace 1.8+) or in solr.log.server in [dspace]/config/dspace.cfg (DSpace 1.7).

Manually delete Solr index files

Set up Solritas (VelocityResponseWriter)

Solritas is a generic search interface on top of a Solr index. It can be useful if you want to explore the contents of a Solr index (core) using facets.

To set it up in DSpace 3.0 (which uses Solr 3.5.0):

• download apache-solr-3.5.0.tgz fromhttp://archive.apache.org/dist/lucene/solr/3.5.0/
• tar xvzf apache-solr-3.5.0.tgz
• mkdir [dspace]/solr/lib
• cp ./apache-solr-3.5.0/dist/apache-solr-velocity-3.5.0.jar [dspace]/solr/lib
• cp ./apache-solr-3.5.0/contrib/velocity/lib/{commons-beanutils-1.7.0.jar,commons-collections-3.2.1.jar,velocity-1.6.4.jar,velocity-tools-2.0.jar} [dspace]/solr/lib

• edit [dspace]/solr/solr.xml and add the sharedLib attribute:

  Code Block
  language html/xml
  <solr persistent="false" sharedLib="lib">

• edit the solrconfig.xml file of each core where you want to use Solritas. Example for the "search" core: add the velocity ResponseWriter and requestHandler in [dspace]/solr/search/conf/solrconfig.xml:

  Code Block
  language html/xml
  <queryResponseWriter name="velocity" class="solr.VelocityResponseWriter"/>   <requestHandler name="/browse" class="solr.SearchHandler"> <lst name="defaults"> <str name="v.template">browse</str> <str name="v.contentType">text/html;charset=UTF-8</str> <str name="title">Solritas</str> <str name="wt">velocity</str> <str name="defType">dismax</str> <str name="q.alt">*:*</str> <str name="rows">10</str> <str name="fl">*,score</str> <str name="facet">on</str> <str name="facet.field">title</str> <str name="facet.mincount">1</str> <str name="qf"> text^0.5 title^1.5 </str> </lst> <!--<lst name="invariants">--> <!--<str name="v.base_dir">/solr/contrib/velocity/src/main/templates</str>--> <!--</lst>--> </requestHandler>

• cp -r ./apache-solr-3.5.0/example/solr/conf/velocity [dspace]/solr/search/conf/
• restart Tomcat
• Solritas should be available at http:/localhost:8080/solr/search/browse/

It should also be possible to use it in DSpace 1.6-1.8, but these use different versions of Solr, so modify the procedure accordingly (and expect other caveats):

Note: In older versions, you may need to specify the queryResponseWriter class as org.apache.solr.request.VelocityResponseWriter (I haven't tested it, though)
