Currently I get the following message running the example "01502_documentQueries":
ERROR LuceneTableIndexerNodeModel Exception adding row to index: null
After that the queries are logging:
ERROR Index Query Execute failed: numHits must be > 0; please use TotalHitCountCollector if you just need the total hit count
I assume the indexing didn't run correctly therefore no index exists. Any suggestions what could be wrong?
BTW, I didn't change the example - it never worked at all on my desktop.
