Possibly somewhat unusual question: I'm looking for a way to query the
number of *lucene documents* from within Solr. This can be different
from the number of Solr documents (because of unmerged deletes/updates/
etc).
As a bit of background; we recently found this lovely little error
message in a Solr log, and we'd like to get a bit of an early warning
system going :-)
The numbers shown in Solr's LukeRequestHandler come directly from
Lucene. This is the URL endpoint it will normally be at, for core XXX:
http://host:port/solr/XXX/admin/luke
The specific error you encountered is why old hands will recommended
staying below a billion documents in a core. That leaves room for
deleted documents as well.
Thanks,
