I did some investigation and found out that the retrieving part of
documents works fine while Solr did not restarted. But the searching part
of documents did not work. After I restarted Solr it seems that the core
corrupted and failed to start! Here is the corresponding log:

There for my guess would be problem with indexing the keywordField and also
problem related to closing the IndexWriter.
