That worked for me. Also the option is —config and not —conf. Fuseki starts but it does not read my existing data. If I execute simple query to get count of triples, I get 0. Also, Fuseki gives this warning - Dataset not found: No session.
If I start Fuseki with —loc option and not —config, then it correctly reads all data and the same query gives correct count. Is there anything wrong with the way I have configured dataset in assembler file? Also, do I need to create 2 different services for normal sprawl query and text search? In other words, can I execute both types of queries in single console or not? -Regards Ajay > On Nov 4, 2015, at 7:35 PM, Andy Seaborne <[email protected]> wrote: > > On 04/11/15 13:59, Kamble, Ajay, Crest wrote: >> Hi Andy, >> >> I tried that but it did not work.
