It would be of tremendous value to my project if this works; I wish I had
time to try it also.

Hi Dan
Thanks for your suggestion but I am not trying to load large dataset yet.
I am trying to see if I can use Jena Full text search with other Jena based
API such as MarkLogic or Virtuoso but seems like it doesn't work as
expected. Not a Jena problem though. My set up is
1. Input file:
Update: I switched from Lucene to Elasticsearch 6.4.3 and Kibana. Both Jena
and MarkLogic Jena works with indexing, I haven't tried querying MarkLogic
with text:query though.
Using Kibana, I could see the number of documents increasing while
importing data with MarkLogic however it is very slow.
Hi Andy
I ended up creating separate implementation for Jena and MarkLogic full
text search for now due to time constraints of the project. I will
investigate further at a later time.
Thank you
Best Regards

Alex,
I can't try it out - I don't have a Marklogic system.
Can you see in the server logs what is happening?

Hi Andy
I had to pull develop branch from here
https://github.com/marklogic/marklogic-jena/tree/develop to get the version
that works with Jena 3.1x.0
then update file
https://github.com/marklogic/marklogic-jena/blob/develop/marklogic-jena/build.gradle
with the following
1. Line 9: change
The maven central artifact com.marklogic:marklogic-jena is 3.0.6 but our
code depends on 3.1.0 - what code is it using?

I am incorrect, and apologize. Virtuoso's Jena 3 driver includes an
implementation of Dataset, and so while application is only using the
virtuoso.jena.driver.VirtGraph and
virtuoso.jena.driver.VirtuosoQueryExecution (and factory), a more flexible
integration is possible. I look forward to
Virtuoso's Jena driver implements the model interface, rather than the
DatasetGraphAPI. is translating the SPARQL query into its own JDBC
interface. You can see the architecture at

Yes, probably - but.
The Jena text index will work in conjunction with any (Jena)
DatasetGraphAPI implementation. 3rd party systems are not tested in the
build.
The "but" is efficiency. Both those systems have their own built-in text
indexing which execute as part of the native query
