As you said yourself it's not installed as dependent package of xwiki-enterprise. Like the documentation indicate this is to be used only if you plan to setup a standalone Solr index which is not what XWiki is using by default.
OK thanks. I didn't find it all that clear from the page I was reading (platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationViaAPT), perhaps because there's not much info on how Solr fits into the XWiki architecture. But my understanding now is that Solr is the search engine used by XWiki and an embedded server is included within the standard xwiki-enterprise packages, but a standalone server can be used if the xwiki-solr-data package is used to configure it for XWiki. Is that all correct?
Yes. Think of Solr as a database. We use an embedded version of Solr by default to make things easier but putting Solr in a different instance can be safer in some cases.
The error you get have nothing to do with that but you did not gave enough details to know what is wrong, specifically the cause of "Error creating core [xwiki]".
So it looks like Solr should get set up the first time XWiki is run, but because of the issues with openjdk9 this wasn't happening, and all the errors were being caused by the expected items then not being found. Restarting Tomcat once XWiki successfully started the first time seems to generate no further errors.
Yes Solr is not a big fan of missing files in its home folder and the best in this case is to delete it (so that XWiki recreate a fresh one).
Thanks,
