Error CREATEing SolrCore, QueryElevationComponent missing config
file
Hi,
I'm new to Solr and am trying to set up a newly installed Solr instance.
When I try to create a core via the web interface I get:
Error CREATEing SolrCore 'new_core': Unable to create core [new_core] Caused by:
QueryElevationComponent missing config file: 'elevate.xml either:
/var/solr/data/new_core/conf/elevate.xml or
/var/solr/data/new_core/data/elevate.xml must exist, but not both.
Intermittently I see the following error first with the above error appearing
"behind" it:
Connection to Solr lost
Please can anyone tell me what I've done wrong?
"elevate.xml" doesn't exist anywhere in /var/solr/data/new_core but I'm
presuming this should be being automatically created as part of this process
using the one in /opt/solr/server/resources (which does exist). Directory
/var/solr/data/new_core/conf doesn't get created at all but
/var/solr/data/new_core/data does.
I can't see anything obvious in the log apart from the above error.
Solr 6.3.0 on Fedora 25 with OpenJDK 1.8.0_111.
Thanks,
Leon Stringer

Hi Erick,
Thanks for your reply.
My assumption was based on my steps apparently working with 6.1.0, i.e. I could
just add a core via the web UI without any other steps being required and
everything appeared to work.
That process, which I accept was probably not correct in the first place, no
longer appears to work with 6.3.0.
However, your recommendation works for me, e.g.:
# sudo -u solr /opt/solr/bin/solr create_core -c new_core -d basic_configs
creates the core as expected.
Thanks again,
Leon

Your assumption is not correct. The Web UI core admin expects that
you've already created the new core's directory and the associated
conf directory below it. Since each core may have a much different
config, there's no good way to pick the right set of configurations,
your schema.xml file which is the heart of your search really must be
customized to support your individual use-case.
Personally I'd use the "bin/solr create_core" script command instead.
Admittedly the admin UI is tempting, but it makes some assumptions.
Best,
Erick
