No such type:
I'm trying to enable full text search on a Fuseki v3.12 instance but I get the error shown below. The assembler is pretty much a copycat of the documentation, with a Lucene text index. The assembler contains the prefix "text: <http://jena.apache.org/text#>".
Is this a bug?
$ java -cp fuseki-server.jar jena.textindexer --desc=run/config.ttl

Hello Laura,
Now that another issue is being examined some data and queries will be needed.
Thanks,

With the above configuration I do not get a "No such type" error, but I get a sort of mixed behavior. Sometimes it seems to work, while most of the times it returns zero results. And I cannot reproduce it either... it gives me zero results except a few times it magically starts working (returning results).
I get the "No such type" error when using a RDFDataset instead of DatasetTDB, but at this point I'd love to understand what's going on here before trying to understand the RDFDataset error.

Hi Laura,
It would be helpful to see the assembler file. Then we may get closer to whether there's a bug.
