Are you sure that the Solr index is really empty? Did you check this via
the Solr Admin tool?

I had the problem of EXT:solr not delivering any results after some
time. It turned out the the problem was a active filter in the TS query:

endtime = (endtime:[NOW/MINUTE TO *] OR endtime:"1970-01-01T01:00:00Z")

After disabling this filter, the search worked fine again.
