Deleting old index data from solr. But HDD spaces doesn`t free.
Hello.
I am deliting old data from solr such way.
String url = "http://192.168.5.138:8080/apache-solr-1.4.0/";
CommonsHttpSolrServer server = new
CommonsHttpSolrServer(url);
server.setDefaultMaxConnectionsPerHost(200);
server.setAllowCompression(true);
server.setMaxRetries(1);
Calendar cal = Calendar.getInstance();
cal.roll(Calendar.MONTH, false);
SimpleDateFormat sdf = new
SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
String query = String.format("publishedDate:[* TO
%s]",sdf.format(cal.getTime()));
System.out.println(query);
server.deleteByQuery( query );
server.commit();
Data disapears feom index but But HDD spaces doesn`t free.
What I am doing wrong?

What you are missing is a final
server.optimize();
Deleting a document will only mark it as deleted in the index until an optimize. If disk space is a real problem in your case because you e.g. update all docs in the index frequently, you can trigger an optimize(), say nightly.
