Hi, I'm facing the same issue as Axel reported in https://issues.apache.org/jira/browse/ZEPPELIN-5437 (but without the preceding NullPointerExceptions)
To be honest, when I first tried remote debug to understand why I don't see results, I managed to debug into the SearchService, to make sure it's not the NoSearchService implementation. After restarting the pod, I got the exception: *LuceneSearch.java[query]:135) - Failed to open index dir MMapDirectory@/tmp/zeppelin-index lockFactory=org.apache.lucene.store.NativeFSLockFactory@5270* *8e8d, make sure indexing finished OK* *org.apache.lucene.index.IndexNotFoundException: no segments* file found in MMapDirectory@/tmp/zeppelin-index lockFactory=org.apache.lucene.store.NativeFSLockFactory@52708e8d: files: [write.lock]* I'm running 0.10, using FileSystemNotebookRepo, and notes are stored on HDFS. Working perfectly with zeppelin 0.8.2... Any clue why? Thanks
