Thanks Alexandre for your minimal config example! I am trying to use it as start to understanding, but I cannot get it running. To make it more explicit:
I am running a freshly installed solr 6.1.0. Suppose I am in its home directory for the following steps: solr-6.1.0$ bin/solr start solr-6.1.0$ bin/solr create -c cinema solr-6.1.0$ cd server/solr/cinema/conf solr-6.1.0/server/solr/cinema/conf$ ls currency.xml elevate.xml lang params.json protwords.txt managed-schema solrconfig.xml stopwords.txt synonyms.txt Here I replace managed-schema by your minimal schema.xml and solrconfig.xml by your minimal solrconfig.xml and restart solr (don't know whether this is actually necessary to activate the new config files). solr-6.1.0$ bin/solr restart solr-6.1.0$ curl http://localhost:8983/solr/cinema/update -H "Content-Type: text/xml" --data-binary @example/films/films.xml <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"><int name="status">0</int><int name="QTime">123</int></lst> </response> So no complains from solr! But the response comes too quick in my opinion. And in fact the data folder still contains an empty index and empty tlog subfolder. Consequently queries fail, too: $ curl http://localhost:8983/solr/cinema/select?q=genre:Drama <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"><int name="status">0</int><int name="QTime">1</int></lst><result name="response" numFound="0" start="0"></result> </response> What am I doing wrong?
